Can you get a test ride an show us a picture of the unweighted wake or wake with a few people? Most ski boats can be weighted down to produce a nice clean wake. The only problem you may have is the wake washing out (getting foamy) on one side or maybe not getting a good lip on the wake.
I have an 86 advanse. It throws a very clean wake. I think it throws a better wake than my buddies 01 Ski Supreme Pro Am 190. The wake holds up nice and has decent vert for a ski boat. I have talked with some people who compare it to the SN 2001 which has really good reviews from this forum.
