You need a bit of cross off to kite, 45 cross off works well and will hold the waves up so the top of the wave is powerful.
In these conditions I leave the kite parked fairly low towards the shore when wave riding, bottom turning away from the kite so that the kite actually travels right to the edge of the window ( towards the shore) before the top turn, this way the kite doesnt pull much at all coming out of the top turn.
I ride like this frontside on lefts and rights no problems, and I imagine if you bottom turn backhand it would be easier, cos you would be facing the kite more.
To ride like this you need a board and wave combo that allows you to bottom turn without kite power and have enough drive off the bottom to hit the pocket at the top.
The apparant wind up the face of the wave can be horrendous in cross off, so the above technique eliminates getting blown out the back of the wave due to overpowering the kite.
If you crash sent the kite out to sea so that you dont get rolled by the wave into the lines, and if you ride without a board leash, consider using one cos if it all gets ugly you can ditch the kite and paddle back to shore.
I use a short board leash that goes to the back of my harness, I dont reccomend leg ropes cos your legs tend to flick around in a crash which can slingshot the board toward you, but this has never happened to me with a short leash to the back of my harness.
Anyway charge hard, cross offs rule imo
