I've been considering moving from my itaste vv v3 to a box mod. I've been told the eleaf istick 50w is the way to go, but, is it really that much better than the istick 30w? At the moment I'm using a nautilus mini but considering a tugboat rba clone to do some sub ohming. Kinda want to keep the Ego thread capability as well, but I don't want to spend too much.
