I use the eroll most of the time using 2.4% halo tourqe. I used to use a clearomizer set up..but was feeling like I was getting too much nicotine..but with the eroll..I do not get that feeling. I am getting sick and tired of filling it all the time..and my dad uses the ego cc clearomizer..and I really enjoyed the draw on it. My question is..is it common to use higher nic in something like the eroll..but use less concentration in a bigger set up like the ego cc? Should I come down to 1.8% for a bigger system? I really like jc's new birchwood cherry (formally blu cherry crush)..but at 1.6% in my eroll..it doesn't do it for me. Would it be more satisfying in a bigger set up? Hope I'm not too confusing..Thank you for any help.
