The RRT-2 is more of a thrower than the Jet-III M, which is more universal thanks to IBS. I got the titanium Jet-III M, but I guess it's the same than the stock one speaking of beam.
I never compared the beams, to my feelings, the RRT-2 has the tinier hotspot and the less spill, so it should throw the most. The selection ring maybe great, but has some inconviences as well. Its action is too easy, the clikcs not stiff enough, you easily jump modes. Then, it works just the other way round that I'm used, from left to right : high-medium-low-strobe standby. Imagine how big the chance is, that you turn from low to strobe? As a thrower, I leave mine on high, normally that's the mode I want to use and I'll turn the right way to step down...
Nothing to say about the IBS : High mode with tightened head, programmable mode with head loose. Easy...
I would also say that the Jet-III M is the more rugged light, thicker walls (if it's true for the stock version as well) and the weak part of the RRT-2 is the selection ring.
Why not get an RRT-0 as second light??? :devil:
