3 blade vs. 4 blade

[89mariah]

Looking to replace the stock 3 blade on my 89 Supra Mariah. Acme seems to be the one. I spend 20% Aggressive slalom, 35% wakeboard, 30% Wakeskate, 15% Wake surf. Any thoughts or recommendations from those of you who have approached the same question of 4 blade vs. 3 balde lately?

Thanks,

4 blades seem to perform better on the bigger "wake board" boats.
