Really? Must be my imagination then... I really thought I was having to rebuild more often than I used to...
I've been using Ti going on 3 weeks and seems to be better so far with me. I use strictly unflavored juice tho.
Its definitely a juice problem. I've been using a vanilla/custard 60/40 vg/pg and my coil (and wick) gunk up within 3-4 days. Have now changed to an all vg of tobacco and very much less gunking.

The sweeter the juice the more it tends to gunk up in my experience, I dump my tank clean the coil and re-wick good as new.
With the new ESG Ti wire, I also started using cellucotton (rayon) at the exact same time. My vape has improved. Before this I was using kanthal and regular cotton.
With kanthal and cotton I was having to change my builds every three days, sometimes every two days and even everyday with heavy vaping. Every once in awhile I would get lucky and go almost 5 days before rebuilding.
I rebuilt a lot with kanthal and cotton because I wanted to keep my vape clean. But now with Ti and Rayon, I can go a week with no problems.
I don't contribute this success on just the Ti wire alone, but with the rayon as well. The cotton is hard to maintain, even with a fully saturated cotton wick...a little too much power from the battery and maybe with the ohms being a little too low on the coil, it can burn the cotton easily. Even with a good cotton set-up, it was easy to burn the cotton wick. This happened a lot when I would change the battery for a new one...suddenly too much power on a mech mod and suddenly a burned wick.
The rayon is much different. Now with the Tilemahos being a tank where you can't see the juice inside, I can tell when a dry hit is coming based on taste of the rayon. I know when to refill the Tilemahos, and the rayon doesn't have to get burned for me to know. It is hard to explain. The vape just taste dryer...not burned, and then I know to refill Tilemahos.
I'm not saying the rayon can't be burned, it just takes more heat to do it compared to cotton IMO. And after a while...like a week's worth of vaping, the rayon does wear out and it will taste slightly burned...that is when I do a rebuild. I change out the wick and coil with both with new ones.
Enough about rayon...this thread is about Ti coils right?
The Ti wire I notice that there is much less 'gunk' on a used coil. But someone can argue that this is because I switched to Rayon (oops I said it again) at the same time and not using cotton. But with the kanthal the gunk would be stuck to the coil and not the wick. I don't see a whole lot of gunk on the Ti coil, even after using it for a week.
I also think that it has a lot to do with the type of juice you are vaping. All VG juice will be harder on the wick and coil compared to juice that has PG in it. Flavoring is a factor as well, and some juice taste better with different ohm coil builds. I make my own juice so because I am using a mech mod (Esterigon), I use a little more PG than VG in my juice ratio for more throat hit. I also add a little bit of distilled water, about 10% to my juice. I'm not blowing the thickest vape clouds, but the thinner juice is easier on my builds. And the vape is just as satisfying.
Vaping is a science when you factor in everything that it takes to achieve a good vape. I figured out how to make a 0.6 ohm Ti coil every time when I rebuild. I use the Esterigon/Tilemahos combo along with my 3 year old rechargeable batteries. I have 5 batteries in rotation...it used to be 8. These batteries are getting old.
The Ti wire uses more wire to get the same ohms as if you used kanthal. And with more wire comes more wire surface to vape more juice, which can also bring more flavor. I bought some (already made) juice for the first time in over year...since I make my own, and it was good, but I thought there was a little too much flavor.
Bottom line is that the Ti wire is awesome! Sorry...this post wasn't supposed to be a book. [emoji4]

great analysis Sad, I totally agree. And dont forget the safety that titanium adds to your vaping
Look under supplies at ESG for cellucotton. They sell rayon and have a picture of a box of the exact same stuff I use. One meter for 0.90 that should be enough to last at least 6 months I would think.
Have tryed today my first res rayon cotton / titanium from e-smokeguru ... I've done a microcoil with 0,25 tit wire (6/7 spires about 1,2 ohm) ... taste and aroma seems better than kanthal / muji cotton ... I'm very satisfied 
next time I'll try a normal res with 0,18 ti wire

Congratulations Frillo. You have stepped above the others who have not tried this and don't know what they are missing.
I told a worker at a vape shop that my coil was titanium. He said that it seemed kind of sketchy. How can titanium be sketchy? This is the same material we are implanting into humans. We are using titanium in a different way however. We are using it to vape. It is hard to teach an old dog new tricks. Someone who is conformed to their ways, the only way they know how to do things is because it is what has worked best for them. It is hard for them to know that there is a better way. And even a safer way. Until they try it and see for themselves.
It would be interesting to see the opposite effect. What if the start of RBA's started with everyone using titanium wire? What if titanium wire was normal and everyone used it without second guess. And I told someone that I started using kanthal instead because it was cheaper. Then I would expect the reaction of 'That sounds kind of sketchy.'
Sorry, Saturday night...drinks are kicking in. [emoji4]

exactly as you said Sad! Thats my thoughts too. People cant accept changes. Workers cant, vapers cant. Its ok of course, they just need time
I still dont know 67. I have to assemble the unit in the right way first on the machine and then see if I have room for esg Ti
I've spent 32 years developing metallic materials for turbine engines and my wife is in medical technology. After reading through this whole thread we've become concerned about the amount of misinformation being presented as fact.
In many ways it's understandable that folks who are into vaping would be more concerned about potential health issues than the average person. After all we have found vaping as a way to improve our health after many years of smoking burning tobacco. Why would we not be highly concerned about health? Still, misplaced health concerns may frighten folks who do not have relevant knowledge and harm the image and future of this great smoking cessation technology. I hope that does not happen.
The three metallic materials most often discussed for atomizer wire seem to be Kanthal (what material scientists generically refer to as FeCrAlY), pure Nickel and Titanium. Having spent my life doing detailed studies and development in each of these material classes my opinion is that none of them present any health hazard when used as atomizer wire. Not low risk but absolutely NO risk. Under other conditions which cannot be created in a vapers atomizer any of them could be found to be hazerdous to some degree. It's a dumb analogy in many ways but many of us live in wood houses with no particular concern but we do become concerned when the house is burning around us. The key is not to allow the house to burn. The next thing to remember is that most common metals can be made to burn. All it takes is to make the particles of the metal small enough, provide oxygen at the right pressure and provide the proper temperature.
Given the right conditons iron burns, nickel burns aluminum burns and titanium burns. None of these metals will burn in a vaping atomizer because the right conditons are impossible to create in an atomizer. None of these materials can be caused to emit harmful species during normal vaping because the conditions that could cause them to do so are impossible to create in our atomizers.
Kanthal, pure nickel and titanium each have special properties which make them potentially good atomizer wire materials, yet all are different and all will provide a different vaping experience.
Personally I use all three wire types in different atomizers, with different power supply devices to meet different goals I have for a specific vaping conditions.
I would like to see folks pay more attention to the unique qualities of each of the wire materials in vaping rather than focus on health concerns which cannot be created in our atomizers. I think that would be better for the future of vaping if it could happen.

Thank you druckle for your insights. Just one question though: Do you think dry burning any of these metals can be a favorable condition to emit the potential hazardous materials? I think this is the extreme that most of us is concerned about.
I dry burn all of these materials but with nickel and titanium alloys I restrict the high temperature exposure to short pulses for a limited time and then wash and brush away the surface deposits from the e liquid. Recently I've mostly used a small ultrasonic cleaner used for jewelry to clean coils and this is very effective with a few drops of liquid soap in water or with alcohol. There is absolutely no damage to the coil from the ultrasonic exposure and the process is quick and costs very little to employ.
In the case of titanium alloys, if long dry burns are used at bright orange to white hot temperatures a flake titanium dioxide will form but this is NOT the nanoparticle material discussed as potentially harmful. These flakes are large, nonadherant bits that can be brushed away in a running water stream. The only problem is that this consumes some of the underlying metallic titanium and embrittles it so that the wire changes in resistance and becomes fragile. It makes no sense to do this and I do not. The oxidation characteristics of most titanium alloys are as follows....at all temperatures below about 1300 F the oxygen slowly diffuses into the metallic surface forming a so called alpha case. There is also a very thin adherent layer of mixed titanium oxides on the surface but again no nanoparticles which can become en-trained in the liquid or vapor stream. This diffusion is very slow at temperatures below 1000 F and takes thousands of hours to have a significant effect on the overall wire properties. Given that our temperature exposures are normally in the 300-400 F range for a few seconds only, no significant effect on the wire properties can occur in our lifetime. For any of these materials long cherry red dry burning is harmful to various degrees to the properties of the wire. Kanthal is least affected and titanium the most affected by such exposure. There is no reason that any of the wires need to be exposed to such conditions.
