how much power did you have in your swing, if you are hitting less than 60% with those clubs you won't get very much backspin at all. Just doesn't work that way on here unfortunately. Try using the flop shot for up close work.
Take a look at the Z Satin 64 degree wedge, 200 credits 50 yard club that is killer, and you are level 83 so you should be able to get the Cleveland wedges that are available for higher levels, they will give you more spin than what you really want but not any of them will give you spin on shots that are less than 60% power.
