I have a Tige 22v and changed prop for surfing but still wanted to ski at 32mph. Went with a 1617 14" x 13.75" and am very happy and comfortable sking at 32mph.
The difference over stock was amazing for surfing.
If you feel comfortable going to 15" dia for hull clearance, I'd definitely go there and think you would still be happy skiing with a 13-14 pitch.
I'm going drop pitch again this summer as the surf difference was so pronounced and just going to ski with other options if it's a problem.
