I have my reo mini 2.1 copper vein and now I want a grand.. I have not used my reo much since the dna and sub ohm faze I have had. Just dusted it off and am remembering why I got it in the first place. After much experimentation I know I like 1.4 ohm resistance on single coils and .8 on dual. What are my best options with the grand?? Will my reomizer 2.0 fit on an lp grand?? Does the lp give me more options?? Part of the reason I put my reo down was that it worked so well I didn't have to mess with it( I know, stupid complaint) I want something I can use different attys on. I like messing with coils, I do not drill holes in anything so out of the box ready to build is my preference. Will my vtc4 batts( flatt top) work in the grand?? Thanks for the help reonauts!!!
