Same issue.. Lots of 540s/720s..

Make sure to turn your head and look at the boat, this should help you stop rotating. Also, try removing the Fins or run the board backwards for a few runs. On my board you really have to edge running backwards to keep control which then should pay off with the fins..
At least I hope so, I haven't surfed much this year. When I do, I've been trying to do a drifter into backside180, and front side 180 with the board reversed but haven't had much luck..
