Had a 760 but I sold it. As a user I'd prefer the 760, as I prefer manual folders to AOs. Hated the clip position on the 760, close to a third was sticking out of the pocket. Action was okay, had to have a litte side to side in mine to get it where I want it. The cool thing about the 760 and the 755 mpr is the hexagonal stop pin, it allows you to rotate it to adjust for lock wear. My 760 was SUPER sticky though, worse than any ti framelock I've ever handled. Overall, I got mine for about $180. Never really use it cause it just couldnt kick my sebenza or my smf out of my pocket. I think itd be a good workhorse kinfe however if you choose to use it.
The subrosa was nice, handled a few. Dont care for recurve blades much though, and not a huge fan of AOs, the only ones I'll consider are the flippers from kershaw/zt. Pretty standard materials though, s30v, ti.
If I had to reccomend one I'd say go for the 760 as thats the one i bought. Just make sure to oil that blade every now and then. However, if you want a benchmade ti framelock, also check out the Bradley Alias if you havent already. The one I handled was super smoothe with no play and disengaged with no stick at all. Id consider it a substantially better knife than the two benchmades, and its made by benchmade for bradley. Just my 2 cents. Welcome to bladeforums!
