I've been reading up on the forum about variable voltage/wattage etc. and found the BiffRocko posts very helpful. So feel that I understand that it's all about the watts achieved and that the voltage and coil resistance just interact to achieve this. So, I've been testing the same tank on my ego twist and iTaste MVP at the same voltage setting. It seems to taste better on the iTaste. Now I'm guessing this is just in my head, but was curious! So, other than the battery not lasting as long on the ego twist, should I experience any performance differences when I set the same voltage and use the same tank on these different devices? Thanks for any help!
