thanks v1john, mind you the e2 drags where shorter then the 808 old cartosorous and still produced more vapor.
heres a tip as well, when using the 2.5 ohm e2, just like br has mentioned, take shorter drags, maybe half the time of what you normally take, see how much vapor you get and then check how hot it gets.
I noticed by shortening my drags on the e2 I still get more vapor without drying out the wick and causing the carto to get hot. its been working like a charm so far. I have been so used to taking 6 to 7 second drags if not longer just to get that feeling that im getting with 2 to 3 second drags using the e2.
one other thing, using 10mg octane juice, i am getting something that to me is more important then a throat hit which i get with the e2 but most importantly I feel it in my chest, it feels heavy and replicates that analog chest hit perfectly. Im assuming since obviously there is more vapor then im inhaling more and inturn getting a harder hit all around.
