I really cannot understand how choosing good 18650 cells has anything to do with sophistication...:crackup:It has much to do with technology, yes for sure, but sophistication?? :wtf:
Rather gaining knowledge from one's own experiences or others who may have had the experience.
From old4570's test the Trustfire Grey and Ultrafire Red performed rather well in comparison to AW cells in both the P7 and R2 current tests. While costing significantly less to purchase.
While I agree that AW cells are the most reliable so far, the word "best" is relative and subjective. If price is of no object then shelling out $12.00-$14.75 per cell + $4.50 minimum shipping might buy you the "best" cell, but it doesn't mean that the cells won't EVER fail or you won't receive a dud. What you're paying extra $$ for is the assurance that AW sources the best cells he can buy and he has better QC methods than other generic brands.
Perhaps after reading that thread you mentioned about some 18650 cell comparisons, you can decide for yourself what is BEST for your applications, rather than being TOLD by others what is "best" for themselves.
I've used a pair of these cells and have found them reliable for anything up to 3.5A drain from my Surefire P91 and the Lumens Factory HO-R5 lamp assemblies. Using the "true 2400mah" Trustfires in your XP-G with only 1A draw on each cell would be a rather pleasant walk in the park for them I would say.
