In reply to mugglewump:
Any preference over battery powered/rechargable? The Silva Runner or Trail Speed models look good, i've been thinking about them myself. I've heard good things about the Petzl Nao and you actually get a relatively decent ratio of lumens to price if you want to look at it that way.
I currently use a Mammut X-Shot which is OK but the highest setting (200 lumens) is only a 30 second boost mode which isn't great for longer technical sections. Also, the brightest mode is quite a concentrated flood which doesn't give me as much field of vision as I would like. It's worth looking at how the lumens are used (i.e spot or flood) and which would suit your needs best
