Yes the longer the wire the higher the resistance will be. I like big wicks like 3mm. rba/RDAs IMO are much much better on a purely mechanical mod. Otherwise you are limited by the current limit of the device which for the majority is under 15w. My current sweet spot is around 20w. Without a doubt you can get a great vape using a VV/VW device. IMO they are also much much easier to get setup on a mechanical as well. No errors and don't have to worry about little tiny momentary shorts you can just keep firing and burn right through them. I use to use a provari when i first started using RBAs and it got to the point where if i saw that E1 one more time i was going to gladly take the $160 loss to watch it shatter on my kitchen floor. even now if im building for someone that will use it on a provari i set it up on a mechanical and then put it on the provari
