Of the four I own (Commander, CQC-8, 12 and 13), I would think either the 8, 12 or 13 would be fine. Thier modified chisel grind takes a littel getting use to but it's be quite easy to maintain in the field. I typically just strop. Of course the 12 has the fame-side lock, and is probably the most robust, however all three have an excellent belly for skinning. I like the Commander, but the other three provide better tips for bushcraft and making more precise punctures.
Personally, I've carried an Emerson since '98, which was my Commander...I'm going back and forth between the CQC-8 and 13, I like the design of both for the majority of cutting chores. The blades are a wider saber grind, giving a decent robust structure, but (I think) the M-Wave was more of a flat grind which would be a better slicer and still give you adequate strength. I haven't had an issue with the current profile and I've employed all but the Commander over here in Iraq with excellent performance.
