Funny I've been debating this for awhile 9P Vs G3.
There's probably more options with the 9P, and I like the feel of a 6P's aluminum more than the Nitrolon. Still the Nitrolon is better for cold and wet hand I find.
If you're looking at LEDs in the future, the 9P is pretty future proof.
As for your range of 1-200 lumens. It all depends on what you're doing and how much you
think you want. If you're like me and haven't seen 200, might be too much.
I know the difference between the P60/P61 isn't that big so i don't know if there's a huge difference in the outputs of the P90/91's.
For me, I'm gonna order up a G3, simply for the nitrolon grip, and I'm going to use it mainly as an incan. And saving $20 can't hurt either
I doubt you could go wrong either way.
Oh ya, the Type 2 finish will wear in time, and the nitrolon will retain it's color.
Hmmm, then again, the motto here is 'buy both'.
