I think the ZT 030X series is the best knife ZT ever produced, and I think many agree with me. The ZT 0301 series was the first time ZT brought back a discontinued knife temporarily, and it sold amazing. I hope the ZT 0303 sells well, so ZT continues this trend brings back the ZT 0302. I would like ZT to re-issue a ZT 0560BW, which I think is a superior knife to the 0562.
I like the 560 more than the 562 based on one stat alone: 3.75>3.5. If they resurrected it as the 0560Ti in 20CV that would be amazing, but I guess would admittedly piss in the 0562Ti's pool a little bit.
I'm with the other guy on the 301/303/350 though. I hate the blade shapes and in the case of the 350, the liner lock. When I think of ZT I think of higher end titanium frame locks and the 350 makes me think more of an Emerson.
