I finished up my S90V Manix 2 tonight and the freehand knowledge is definately helping me get up to speed pretty quick. After de-burring after sharpening on the 220 it was tree topping, S90V just loves to get sharp at coarse grits. I went all the way to 6000 tape and it whittles hair real nice, but S90V just doesn't seem happy with a polish. I've been doing 320 to 600 grit diamond edges on it freehand to get agressive tree topping sharpness, and it just doesn't seem worth the effort to polish it out. M4 on the other hand I can't wait to take to .05 microns for a real test of just how sharp I can get a knife on the edge pro.
