I program spoilers (both ailerons up) about 10-12 degrees. I also program a little down elevator (about 2 degrees) on the same switch. I hit the switch on the downwind leg, make my turn and land. This makes landing very simple and I have never had a problem with the plane stalling. It just just settles in with a nice glide slope and lands. It really helps when there is wind as the spoilers push the plane down (kill the lift) at a very controlable rate. I use this on all my floaters - WH Edge 540 and WH Sukhoi.

Whith CG back far enough to fly 3D well, these planes want to float all day. Try the spoilers, I think you will like them. I love it.
