your 150 lbs.?? about 5'5" or better in length . if you have surfed before understanding the drive on the back of the board is old news. if not
then let the lesson begin. at your size just about any thing will work.
strapless ?? my jibes are weak but trans. air board flips are better. both are challenging. kite control and timing through the jibes need to be
spot on.
i curve toe side and at the unweighted apex move my back foot to front . for a second your feet are dead centered and getting the your NEW back foot
IN( 3strap set up) is just hard for me. strapless is easier but chasing the board gets old.
a narrow board will be faster not critical but the kite will like it better , the turns are gonna have you in the water alot, coming in really close
is out the fins will bottom out .
QUAD finn set up is def the way to go, well separated front to back.
upwind in light air with the right set up is where drive comes in, not as much work as a fat TT but rewarding if you can keep the kite happy
