Longtime lurker here from EDCF! A few years ago I bought a Fenix TK20 on the strength of the recommendations I saw on the forums, and have loved it ever since. While it's still going strong, I was wondering if newer technology might offer possible upgrades for my trusty TK20. My folks are also asking for flashlight recommendations, and while I would have said the TK20 without hesitation, the fact that it's discontinued makes it difficult. My main consideration is: AA batteries, and primarily throw rather than flood. So far I have a few possibilities in mind: 1) Another TK20 - If it works, why not? However I have not been able to find any place to buy more. 2) A 4sevens Quark Turbo (or even just a Quark AA2? A Quark X AA2?) - This seems to be a forum favorite, although I've seen heard rumblings about QC issues. 3) Any others you guys can think of? Thanks in advance!
