I play the CG12 52*/10* and the Vokey SM 58*/12*.
Each have certain qualities and I use them under different circumstances obviously.
The Cleveland hits the ball a lot more 'clean' if that makes any sense.
On a scale of 1-10, spin is a 9 and control is a 10 for me. I can stop a shot out of a moderate rough at as little as 100 yards within 3 feet. Shorter than that, it will roll a little more. Fairway shots produce more spin of course.
I do not play the Vokey (which doubles as a SW) unless I am within 70 yards. I play V1x, and it can cause more back spin than I want when struck full (for me 90 yards). If the green is sloping even slightly towards you, it is very easy to hit 1/3 to 1/2 into the green only to end up on the front fringe.
However, on short chips from around the green to 30 yards out, it is priceless. You can flop over a bunker from some thick grass and hold the ball really well, even if the green is sloping away. So for this, I love it.
I'd be interested to see if the Cleveland 58* has similar characteristics.
One thing I will say to differentiate the two, I love taking the Cleveland out of the bag on a shot. A lot of times I wish I had been a little farther or closer to the green just so I could play the Cleveland as opposed to the PW or Vokey.
The Vokey SM is probably not something that everyone would like, but I could not imagine anyone not liking the Cleveland 52* that I play.
Hope this helps, any questions, let me know.
