26 has been my go to size for quite some time. I have everything from 24 to 30, some Ni200, but a small amount to try tc, Ni80 in 26g, the ss I mentioned and the Clapton stuff. I'll probably end up going back to my 26. 24 is like trying to heat up a car coil spring to me. I even have some flat kanthal which I used to make some tiger wire once. Didn't care much for that either. Simplicity, I guess for me, is the name of the game.
Pretty much the same here.I have a large amount of 30g left from back when i first started,when i was rebuilding protank
coils,still have a large amount of 28g because i thought i would never change from it haha,i bought a 100' spool of 28g Ni200,and i used maybe a foot of it before i realized tc wasn't for me,then i discovered 26g and have never touched any of the others.I forgot,i also bought a large spool of 24g,and like you,seemed like i needed way too much power to get a decent
vape from the 24,so that was very short lived as well haha,26 just seems like the perfect sweet spot for me.I recently got some 26g stainless,and tried it a few times,still up in the air on it though,i haven't used it enough yet to know if i really like it or not haha.
