yatsunil, seeing as you've reached your decision, i hope you don't mind if keelhaul your thread and take it on a slightly different tack? =P i'm looking at a similar set of three lights, except in place of the incendio, i'm looking at the 4sevens quark 123 (regular, single cr123).
i've got a quark mini aa (the only "real" torch i own except for my itp a3 eos =P), and i love that little light, so i expect similar quality from the regular size quark.
as far as i can tell (i'm sure i'll be corrected if i'm wrong on any point), the regular quark also has going for it: current controlled "low" modes (better efficiency than pwm, which the other lights use). great super-low "moonlight" mode. "lego-able" in case one day i decide i really want a forward-clicky instead of a reverse clicky.
of the other two, the neutron 1c really inspires me for it's super-low "firefly" mode (comparable to quark's "moonlight" mode). walloping high of 255 lumens. but on the downside, it's a bit bigger than the other lights (i'm looking for something "jeans-pocketable"), and the comment on this thread about the fact that the battery makes direct contact with the pcb rather than with a more robust metal "pill" did also concern me: (

the other thing that might colour my own decision about which light to go for in the end, is that i intend using plain ol' primary CR123s, not rechargeables. i know it's been said that you can get better performance, yada-yada, but i want to keep things as simple as possible, and going to CR123s from AAs is a big enough step for me just now =D
i think i'm leaning towards the quark, but wanted to see what others thought of the points above, if they think i'm making too much of any of them, or even if they think i'm really missing another cracking alternative...
