I would go with the mannix 2 myself. One of these days we should sit down and discuss steel. I have a pretty vast collection and have handled/owned/traded/sold more knives than I ever care to count. I always end up with a spyderco. I have been sold on them.
Another option would be the Al Mar SERE I have carried one of those for 3 years and it is beyond all accounts the perfect pocket knife for me.
Man - if I could find one that wasn't Saber grind, I'd probably get it, but the Sprint runs with flat-grinds are super-expensive and I've not seen any that justified the nearly $200 that folks are asking for them used (since it was a limited edition).
I'm looking at the Kershaw PackRat and the Spyderco Sage for a couple of smaller knives.
I think I may end up with a few to play with before this is all over with.
