I guess no one has heard of the Klutch flashlight before so I believe I've finally narrowed my decision on my next light to these 2. I want a rechargeable with decent run time, good throw and adjustable lumens. I like the looks of both these lights and have read some of the reviews which seem favorable for both. I would prefer to have a light that can tail stand but that's not a deal breaker. I don't think I need the 12 adjustments of the Fenix but it's nice to know it's there if I want it. One thing that does bother me though is the post I saw where someones TA21 was defective and had trouble replacing it. If there's a bad one out there I'll get it :sigh:. I do have a question though. What is the standby life of the Aw 18650 li-ion? I'll probably get a few so I can keep them in the drawer but want to know how long they'll stay charged in there. Thanks.
