Don't know about 'best' but from my experience - Vapage's 'gold universal' built for bottom feeders, has been the best one I've tried so far... comes in a few different ohmages
I've had the 2.0Ω one last over
three months running at @4.0V No guarantees though... although you might check with Vapage for their warranties - you can get 6 months if you register - it appears - but likely not with LR attys...
At any rate, this one is well built without any off tastes and works great on my Reo and as a regular atty as well on the eGo.
