Re: Seriously thinking of picking up a Ra clicky...any thoughts before I take the plu
I have the 170Cn and think you'll like it a lot.
The light is designed to work well with rechargeables, so it would be worth picking up a couple of AW RCR 123s and a PILA charger if you don't already have them.
The Surefire filters and diffusers (F04 / F05 etc.) are also a good fit. The F04 will give you a nice floody beam, and I find the F05 red filter handy for astronomy.
I don't know if there are any upgrades or new versions in the offing - a 320 lumen XP-G based beastie would be nice, but as always if you keep waiting for the latest updates you'll never buy anything. In any case, should you ever feel like upgrading later on, you won't have a problem selling it.
Beyond that, you'll have great fun programming it and wishing your other lights had such a flexible UI.
