for 701, I have jet dynamic grate and extended ride plate.. Not thrilled with the ride plate. stability is nice and turning good. but porpoises easily on straight line and with two washer in the back to get rid of porpoising, gets a little squirrely for the newbies who ride it. Then they come off dissing your awesome ski that yu put about 4000-5000 grade in all said and done. I heard the pro watercraft ones are supposed to be goood. Thinking about getting one myself. don't get protec, hated mine. I have not heard anything on WCoT plates.. good questions, now that there are some other options out there nowadays..
