This has probably been covered, but which one???? I was looking at getting either one of these for my PSK. I like the the toughness and easy function of the Peak (I carry a mag AAA in my EDC), plus batteries are very easy to get. On the flip side the size of the Micro is nice, just something about the exposed bulb breaking on a drop (Murphy loves me) and the push button on/off that might come on and drain the light. Sort of on the fence with the multi function button to. My PSK will be in the mini mess tin from BCB (Brian hurry up and get those, suspense is killing me <img src="/images/graemlins/smile.gif" alt="" /> ) so size is an issue, but not as big as reliability and durability. Thanks.
