For a folder, I have been really happy with the VG10 on my spydercos. I did find that it prefers a slightly toothier finish instead of a mirror finish when sharpening though.
For large blades, as much as it isn't a true stainless, Infi has been serving me quite well despite being sweated on , rained on and used hard! <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
I agree the Spydercos with VG10 are good. I still don't own any INFI so I can't say anything about it alto everyone seems to bow to it. One of these days.....
