One additional advantage of the Eneloops is very low self discharge. For those doing shows weekly this may not be a problem; for those of us who work more sporadically, my system of a “Charged bag” and a “Dead bag” works even with gigs months apart. For standard NiMH batteries I would be less comfortable using a battery I last charged 6 months ago.
+1 on the Eneloop Standard (white). For high drain things like digital camera flashes the pros allow the flash to recharge faster; for typical production wireless usage, the extra current capacity of the “pros” isn’t worth it to me.
