In addition to what has been written above, which I agree with, I can tell you what works for me. First, I never chip. I always pitch. Second, I always use a ball with at least 3.5 dots of spin, which looks like you already do. Third, here's how I calculate a distance for a pitch:
- For shorter pitches (~5 to 7 yards), I add 3 yards to the total and hit the appropriate percentage.
- For medium-length pitches 8 to 12 yards, I add about 2 yards to the total and again hit the percent for that shot.
- For pitches of about 13 to 15 yards, I add 1 yard and hit appropriately.
Virtually 100% of the time (there are exceptions), I'm hitting the pitch with full backspin. The above system has worked well for me. By the way, the above assumes that the pitch is from the fairway. If it's from the fringe, I have to back off just a bit on the numbers. As Jim correctly notes above, pitches from the fringe go farther.
By the way, I have the same Cleveland wedges as you do. The above approach is with my 64-degree wedge, which has a pitch rated at 17 yards. I admit as well that some of this is by "feel." In other words, on some holes I may slightly adjust the above formula, depending on variables such as elevation change, if any.
There is a caveat to the above. If the slope of the green around the hole has a drastic rolloff or downslope after the hole. I'll probably opt for a flop instead. For example, on the 4th hole of Chambers Bay, if my ball ends up in the fairway portion above the hole, I always use a flop from there. I would never attempt a pitch.
While I think a pitch has a better chance of holing out, it's also is going to have difficulty stopping by the hole on that green. The flop, however, will stop pretty much dead, leaving me a tap-in birdie.
I hope this helps. If it does, great! If not, feel free to ignore. I'm just passing on what has worked for me.
