Pure and simple, anyone know why, at least to me, it seems every time I hit a rta or rda mouth to lung it seems really harsh unless they are using a high percentage VG liquid. Any particular reason why? I can hit my Iclear 30b and then hit my Lemo with the same 50\50 mix and it just seems harsh to me. I have used people's rda's and they work fine unless it's more than mix, then it's very harsh. I don't seem to mind PG in cartos or bottom coil tanks, but rebuildables seem to act different. Now a lung hit with a Lemo is fine, regardless of the mix %. Any info would be greatly appreciated. Thanks!
