Yeah, Ed is right. The speed settings that are bantied about in the forums are only guidlines. What folks should do with their particular boat is set the speed at a level that allows the wake to clean up AND that everyone can surf at.
TYPICALLY, white wash in FACE of the wake is indicative of a too slow speed setting. A ton of weight is not necessary, however, in the event that increasing speed alone doesn't clean up the face of the wake then MORE weight on the surf side of the boat is most likely needed (then go back and set speed again).
Matt, in your situation you had adequate weight. I would try speeding up the boat until the face cleans up...then if it feels too fast or noone can ride the wake at that speed, gradually slow the boat down until you reach the slowest setting that will allow the face to remain clean. I know that on some boats, especially heavily ballasted boats, they require that you EXCEED the surfing speed setting to get the wake to clean up and then let the speed settle back down.
Keep us posted on your results!
