I vote for the pinnacle. Its a hell of a tough knife. The titanium handle is not only strong but has good ergonomics to it and it gives you a good grip due to its bead blast finish. The blade is just as beefy as the handle, but with the proper sharpening will cut pretty much anything well. Its got a good thick cross section to it all the way out to the tip, but the geometry of the grind keeps it from being overly thick anywhere. The swedge on the back of the blade looks a little funny at first, but what it does is make a for a super strong point that still penetrates well. Its sort of a reinforced clip point.
My favorite thing about this knife is its balance. Its balance point is right at the stop pin. Very few heavy duty folders have that good of balance, they're usually very handle heavy.
The lockup is very strong but easy to disengage one handed ( when you want to that is, not on accident). The first few times you push on the liner it seems stiff as hell, but once its all broken in it works great.
plain edge or combo edge you won't be dissapointed.

It'll feel better when it stops hurting.
