1. I think the first place should be given to Lil'T with Titanium integral compression lock and a BG-42 blade. This was also considered as a candidate by Sal, IIRC. But, could be a remote future.
2. Old Lil'T, G-10 or CF handle, grey or black.
3. MiniManix (or Manix). Would be nice too.
4. ParaMillie. Wasn't it planned to be with a M4 steel?
5. Native. Would be the number one for me, but not in present design. I would wait for an advanced version. I guess, something as Delica 4 handle with double liners, and shape inclined towards a MiniManix, or BM MiniRukus. Probably the best candidate for a Spyderco's equivalent of Sebenza, something like a Spydenza.
Any blade shape is OK, maybe the best would be a high hollow grind.
The present Native is supposed to be a platform for a S125V steel. There is no need for checking BG-42 - a CF BG-42 Millie proved the superiority of the steel and the design. As a matter of fact, the results of the testing was published on the german Messer Forum - the BG Millie won over the S30V even in edge retention. This result should be re-checked, someone as Cliff, because one is testing the same knife, with the same geometry, but different steel.
General remarks.
1. The BG-42 is not a steel for cheap knifes, IMO. It makes sense to make a Spydenza, a high tech folder. In that case, handle should have torx screws, not rivets. Should be either titanium or CF or G-10.
2. One should shoot the BG-42 for Rc 61, as was for BG Millie. Then, the BG-42 shines.
