1. Depends on your chipset.
2. Nothing yet, I have a ton of nickel that I'm mostly satisfied with, so I won't be getting any until my stock is drying up. The bad part is I like gennies, which require some dry pulsing, and that is apparently not a good thing to do with titanium. I might have to stick with my twisted nickel on those.
I got my titanium yesterday but just got to do a build this morning.
First impression - this stuff is like working with a door spring until it is "tempered". It's way springier than tempered Ni200, by far the toughest thing to work with, for me, to date. It also has a significantly higher resistance than Ni200. An eleven turn coil on a 14 gauge needle, about 2.5mm, came in at about an ohm, .983 on my USA ohm meter and .92 on my Invader.
I ended up oxiding the wire over the kitchen stove and have got to find a better, more controllable way. I wrapped the coil and installed to an Erlkonigin clone then wicked it up with rayon. My first try was at 250F, 15 watts. Lots of vapor, no flavor. I kept an eye on the power output and it's pretty solid so the wicking is good. The most important thing, for me, no metallic taste!
I'm still doing what I call the "ErlK dance", balancing the wick to allow good wicking, not leaking and maintaining power. That's my only complaint with the ErlK for a single coil device. I'm also still playing with power and temperature. It stayed solid at 25 watts but was too hot for my taste. I've increased the temperature to 320 and it's doing fine there at 22.5 watts, pretty respectable for a single coil tank. The flavor is good, not outstanding, so some more fooling with temperature is needed. I'm using my favorite DIY liquid at a 60/40 ratio.

I will be using it on the eVic VT since it has a dedicated ti setting. I think for the zephyrus I will do 7 wraps 28 awg around 2.5mm to come out at .4 ohm and for drippers 6 wraps 26 awg 3mm to come out around .25 ohm. I was also thinking about clapton 28 awg over 26 awg for drippers.
Must be 30 awg wire? I have heard that you are supposed to torch it a little to make it easier to work with.

I see a lot of conflicting information on torching Titanium... Maybe a Bic lighter would be safer haha.
I used 30 gauge but will switch to 28 gauge on the next build.
Somehow the carbon that a Bic lighter produces doesn't appeal to me very much, LOL. The trick is to oxidize to goldish or blue, not carbon coat

I feel like my torch would overdo it immediately :/ Well, I still need to get some wire and try it, but I have way too much nickel haha.
I use .39 Ti from German, never torched it or had the need for it, at the moment I like spaced coils with 85% VG.
Another thing I discovered lately was a rly bad and hot taste while vaping, never taste it before, I checked my atty giving small pulses with TC on and without a wick just for testing and after 6 or 7 pulses suddenly the coil becomes yellow/red and yes after this the coil was gray oxidized, haven't happened again after this but I think it has to do with a bad connection on the atty and not the Waidea VF.
I'm a little bit more carefully now.

14 Wraps of titanium is a bit overkill. I use between 6 and 8 and my resistance never is over 0.41
That's my sweet spot

When working with kanthal I normally ohm out the amount of wire I want rather than count wraps, a lot easier in dual coil devices, but with Ni and Ti I don't have anything, with leads, that I'd trust that low so I just guessed. Like everything else, it's a learning curve. I tend to run higher resistances to extend battery life, I'm lazy and cheap!

I use 8 wraps of 28 gauge titanium or if I'm feeling sporty 7 wraps of 26 gauge. Lately I have had the feeling that 7/26 is my sweet spot.14 Wraps of titanium is a bit overkill. I use between 6 and 8 and my resistance never is over 0.41

Thanks for the info, I will be building similar size coils. This is definitely my new favorite thread!
I'm a noob to dual coil RBAs, but the first build I was able to fit into my Zephyrus was 2x 8(I think!) wrap 26g with 2mm ID, ohms originally at .16, now it's reading at .15 (I did this build last Saturday, and it's my main vape. If I had to guess, I'd say somewhere in the range of 20-25ml of vapeage). Even with 2.5mm I was hitting the edges of the chimney. I haven't had any issues with it keeping up, this thing seems to wick like a BOSS.
Edit: Build is with spaced coils. You may have better luck if you're planning a contact coil, cause I think it was the outside corners that were hitting the chimney.
Super glad to hear this!
I've never done a 26 gauge coil with any wire but with 28 gauge it was tight getting them into a Fogger 4.1. I use spaced coils, only, so all I did was compress them down a little, still spaced just a little closer.
Thanks, will let you know how I get on
Should have been here by now, maybe postie has forgot me or lost it
Indeed. I might be ordering some sooner that I expected. Having a LOT of trouble building a Marquis with nickel :/
I use a torch & the easiest way have found is to cut a length
Make a loop & hold with pliers or tweezers , its nice a stable like this & not jumping around
Then hold the wire still & just run the flame around it with continuous movement
It turns gold quite quickly & when parts start turning blue its done
Have tried a few different ways, with this being the easiest / quickest for me
