Help choosing a new prop

We have been converting a 1992 Supra Sunsport from ski to wakeboard setup for about a year now. Added tower, stereo, about 1000 lb ballast. No problems getting out of water wakeboarding but now that we have chewed our prop up pretty good, I want to get a new one for hubby for birthday but not sure which one to get...size or brand. Stock prop is 14 rh 16 3blade. PCM trans 1-23-1 gear ratio. Supra advice is 14x14 4blade. ACME advice is 13 1/2 x 14 1/4 4blade. Supposedly our trans can handle either one but I was shocked at prices so I wanted to know if anyone has suggestions for brands, sizes, #blades, etc. I don't care as much about top end speed as we wakeboard 50%, cruise around 40%...only have 2 slalom skiiers and they should be fine when ballasts are empty. No real issues getting up on boards now but can often slow the boat when carving out...perfect pass may help here but one thing at a time

13.5 x14.25 is going to give tons of torque and get you up no problem and hold speed, but you will lose almost all top end IMO. i'd get something a little less on the low end b/c if you ever ride with no weight it kind of sucks. i like acme products personally, but i know OJ is great as well.
