For future reference, I do already have a ROP but am considering something a tad bit more wieldy. The Rattlesnake doesn't really strike me as being any better in that regard. Weildy, rugged, and not having to baby it to prevent kaBOOM events, mostly.
Yeah, the M6 is a better mod platform, but... M6 moddery strikes me as hilariously expensive.
If you don't already have an M6, I would recommend it over the 10X for one big reason - the reflector.
Yes it would be nice having the low/high available as on the 10X, but for high-output light like these two, the throw capability would be a big factor for me. Although I don't have a 10X, it stands to reason that since the reflector of the M6 is larger and deeper than the 10X (since there is only one), I would say that it would easily out-throw the 10X. Besides this, the M6 creates one of the nicest beams known to man.
The design/form factor of the M6 is also much better IMO. Regarding the expensive modding, my favorite setup is the HO-M6R on 3x17670s. This really isn't too expensive with mcocod's holder ($29). Then you just need the LF lamp ($25) and 3x17670s ($30). I wouldn't call that too over the top as far as mods go.
The icing on the cake with the M6? The ability to run an MN15 for 2.5 hours on primaries. :huh:
Downsides of the 10X vs. M6 (for me):
- NiCad battery instead of Li-ion (memory, requires special treatment, etc., such as you can't top it off)
- $90 for a replacement battery
- Polimer body vs. Aerospace grade aluminum body of M6
- Only 20 minutes runtime on high vs. ~40 minutes on M6 with HO-M6R
Just my 2c.
