I recommend the grand above all, because it's easy and robust. I once asked Rob to sell me adaptors because i didn't want to damage the threads changing atomisers so often. The easiest solution and it avoids any messing about with changing bottles etc is to have your main melon vape in the bottle and just drip what you like into the RM2 or A7 or such as you fancy!
A grand over a vv?? yes, because you can just wash it in a tub of water and it'll work! My vv is for weddings and funerals only!
