I aplogize for how many times this has probably been addressed, but I can't find a direct answer. I'm new to e-cigs, bought an Ego kit from Puresmoker over a year ago. Couldn't get myself to enjoy it, but am trying again. So, I have questions: I am using a 1.5ohm atomizer and would like a little more throat hit. Do I need to change to a cartomizer with more ohms or what? I've tried a 2.3 and 3.0 carto and the smoke is less and the hit seems to be less as well. Is it my setup or does a 1.5 atomizer hit better as it seems to me? Thanks for any help you can give to a dumb newb without flaming me.
