The OP is using a Level 40 RZN Red at 3.5 spin and 5.0 distance. A L8 64 degree wedge should be more than enough with a proper mapping. I wouldn't worry about the new level 29 64 at all.
Quick little shots with a L8 I rented on very fast greens and Nike 81 ball. L8 64W is more than enough if you map it out (which I haven't). https://www.youtube.com/watch?v=YWEM3Tmrt1M
