Just picked up a Fenix TK12 to replace the Malkoff MD2 as a bike light. There's nothing wrong with the Malkoff, I just got sick of taking it off everytime I wanted to go for a run at night, plus the TK12 has a tighter beam which is what I'm after anyway.
Also picked up a Fenix PD20 R5 to replace the Quark AA2 Tactical in my EDC bag. Again, I got sick of taking it out of the bag everytime I wanted to use it around the house. So, the PD20 is the new resident in my EDC bag, which actally makes it a little lighter. Got about 50 CR123s I've had in the drawer for two years, time to use 'em.
