I just received the forward-clicky switch for my L1D/L2D. It wasn't too difficult to install, and really improved the functionality of the light, at least for me. I think this switch would work much better in the L1T/L2T. I have found that I unintentionally cycle through the modes when I use the switch for momentary-on. But it is much more "tactical" than the switch that comes with the L1D/L2D.
I REALLY DISLIKE reverse-clicky switches. I was trained to use my flashlight in short bursts so I really like a momentary switch like most SureFire's, have. A forward-clicky is also good for short bursts. But a reverse-clicky is pretty much worthless in a tactical setting. It takes two slow, LOUD clicks to turn the light on and back off again for a short burst. Not good if you are searching for a potentially armed suspect.
I think a 2AA Tactical light would be a great idea. I love how bright the Fenix L2D is, but the multiple modes and reverse-click have got to go. Better knurling and a removable grip ring would make it nearly perfect. Using the TK10 in the "cigar-hold" using the grip ring is a little uncomfortable after five or ten mintues. A 2AA body would be smaller in diameter than the TK10, therefore more comfortable in extended use.
Sorry about my rambling, but I have had this same thought for a while. Maybe someone at Fenix will take note of our comments and do something about it. We can only hope.
