Everyone has their own opinion on detent, some pure flippers are really strong so these days there's a lot more variation now out there. I tend to like a strong detent because I've had a blade or two open in a pocket before under activity in the field. The two 761's I handled at Shot I felt were weak, about the same as my old 760. Obviously we're seeing some large detent variation in user reports. Hopefully BM will address that as they get more of them made with user feedback etc. I know ZT has said in the past that we'd be surprised how many little tweaks they make over a products life and I'm sure BM is no different.
I think BM really went for a very clean minimal classy design, and on that front they nailed it. It's a very beautiful knife, the blade is not too thick as so many folders are today, and it's grind should make a really good slicer. Lots of attention to detail. If the detent was strong as some obviously are getting I would not have a big issue with tip down. I still feel the clip at the pivot end makes for a more uncomfortable grip in extended use. However, in the 760's case the clip is machined with rounded edges so it's better normal clips.
My knee jerk thought is that $330 street is pretty high, but it's subjective, and as long as people buy them it's not priced too high. I can say that after handing one, if it had tip up, dual thumb studs, and a good detent I'd have bought one. Two of those issues are already taken care of at least with some examples, and I suppose it wouldn't be that hard to have someone tap a couple holes for a second clip location either. Something I always wanted to do to my 760 as well.
