Appreciate the suggestions, man. Keep 'em coming.
I'm currently using 50/50, might be 60/40 on the higher PG side. (Part of why I'm a little confused here)
I just can't get high VG to wick as fast as I'd like it too in the Lemos, so I gave up. I hate having to do primer puffs.
Bigger coils, in the sense of bigger meaning more surface area, does give better flavor. That's one of the reasons why I went the route I did, and why parallels work real well as flavor chasing single coils.
When you say bigger, what do you mean? Wire gauge? Diameter? Overall mass?
One thing I'm not going to do is tighten the airflow. The main selling point of the Lemo to me was the huge airflow. (And bigger Kayfun-ish deck)
I remeber setting the coil about 1mm above the airhole. I can get smaller ones even closer without too much worry about melting anything or shorting it out. If I lower this one any more, I have the feeling the crazy heat capacity is going to run wild.
I started pretty low, and there's practically no flavor up until about 28W.
My current setting is 35w, at about 6.4V. My device won't set it higher than 47.3W before it hits the volt cutoff, but the juice still isn't burning or cooking. I've been trying various settings all day without much luck.
Yup, pretty much all you posted makes real good sense. I'm still at a loss.
When I'm done with this tank, I may just end up switching back to my old coil build, but I'd still really like to be happy with this one.
To some extant, bigger coil will give you more flavor, because more juice is being vaporized. A good example; 28g wire 5 wraps vs 24g wire 7 wraps. But at some point, going with even bigger coil becomes pointless; 24g 7 wraps vs 24g 10 wraps. Imagine drinking 7oz of Pepsi vs 10oz of Pepsi (7 wraps vs 10wraps); you wont get more flavor from drinking bigger gulps. Now if you went from 0.05oz gulp of Pepsi to 7oz gulp of pepsi, then you would be able to taste the full flavor of Pepsi. The reason you not tasting as much of pepsi at 0.05oz, is because not all taste buds are equally saturated for your brain to register the full flavor from Pepsi.
Now i vape at 25watts (24g 7 wraps, 0.71ohm spaced coil). If i go to 30 watts or a little higher, then vapor is warmer and juice tastes better. But warmer juice taste better, just like food tastes better when its warm/hot instead of cold. Our taste buds react to flavor better to hot foods then cold foods. Try warm sushi roll, it tastes 10 times better then a cold sushi roll. I'll never eat cold sushi ever again.
And if its not priming fast enough, then you might want to re-adjust your wick. Take a paper clip and stick it down the center of your wick so it hits the bottom of the juice hole. The juice channel must be clear of wick material.
You can also twist top cover of the tank towards open position till you see air bubbles going in to the tank, close it, then twist it open again to get more airbubles. Its a pain the .... but better then priming.
Also try bridge wicking or some call it Navy Nest, it looks like a birds nest. This way you have double the wicking material and more juice, thus less chance of dry hits.
If you still having issue, then do what i did, and mod the bottom portion of the lower chimney that screws on to the deck. Do this on both sides.
I will be doubling the size of the juice holes next time i re-wick, to increase juice flow when its cold out side with Max VG juice.
Edit;
Almost forgot. Different length and diameter tips will also change level/% of flavor of the juice. A longer and narrower tip will give you a more concentrated flavor towards the taste buds that are designed to register specific flavors.
Short/stuby tips that are wide open, will spread out the vapor across all taste buds, thus you will taste less flavor. On cloud chasing RDAs that have giant wide open tips will improve flavor, because you getting far more volume from an RDA that is designed for cloud chasing at much higher wattage. But we are strictly speaking of Lemo here.
At the end of the day, IMHO, this tank wasnt designed for big coils and high wattage like an RDA. This is why i think you getting dry hits with your current coil. But you can make improvements as i have to work out the bugs, so it can handle bigger coils and more wattage. After all, vaping is a hobby.
I love the lemo because it's my single most stable atty for nickel builds
