Don't have the shift-tech's, but the ducatidesigns adjustable pegs are awesome.

I have size 14's. (48 or 50 in Euro size) I got the 30mm race set which drops the pegs down about 1 inch. Or back and down a 1/2 inch. Or back an inch. Or up an inch, etc., etc. The arm goes around through many different angles.
