Yep its not so much sub ohm , but more on the way you inhale. If your direct lung and sucking in vapor for 10 seconds then perhaps a higher nic is going to be to much, but if your doing mtl and a 3 second pull more nic can be tolerated more. Personally I do mtl on rta's at 23 watts with 24mg nic and it's perfect. I have tried sub ohm and direct lung inhales with 24mg nic and tbh I found the whole experience weak . I guess sucking in all that air diluted the TH, so it wasn't for me. So I guess for me, that I can handle the hi nic, hi power dl inhales from a throat perspective but probably would feel the effects of to much nic as it builds up, maybe eventually causing light headedness
