Paul - I hear you on the corrosion resistance thing - if i didn't practically live in a desert i would probably be a lot more keen on INFI - for corrosion resistance at that level of toughness and abrasion resistance, it seems like INFI pretty much eclipses every thing else that i can think of. My S6LEs have a little patina starting where my thumb rests on the spine in front of the grip, and again in the recess of the choil... if i lived someplace humid or near the ocean where any exposed steel becomes covered in red scale, i have a feeling i would develop a keen appreciation for corrosion resistance...
