Thanks TEEJ. The light spill in that photo is impressive indeed. I have crawled under my house ( almost identical type of space/environment as in your pic, including the dust particles :P ) with the TK12 and the beam profile is quite similar I guess, albeit less pronounced and definitely with less spill.
XT11 certainly looks as though it retains a nice amount spill despite the reportedly awesome throw. And I am very interested in the UI. My Fenix is great, but I never quite gelled with the idea of twisting the head to change modes. Ugh... my bank account is not going to like me this month!
