I'm not a fan of the thumbstud being only a blade stop, and isn't meant to function as an actual thumb stud anymore. That was the kicker for me...I'm a thumb stud guy, A flipper is nice but without a thumb stud I'm pretty much totally turned off.
If they're not going to make the knife so that the thumbstuds are usable to open the knife, they should just go with a pin in the handle. It'd look much cleaner.
Personally, I'd rather they just got rid of the thumbstuds altogether and just went with a blade stop pin in the frame. I HATE knives that use the thumbstuds as bladestops.
