Are you strictly concerned with wake characteristics, or are you looking at overall slalom performance which would include tracking, etc...? If you're just looking at wake shape, go find yourself an early '80's Avenger with an outboard. That was our ski tug for 20 years (no bouys around here). Tournament boats don't come close to the small size and softness of that wake. It doesn't qualify or pretend to be a tournament boat due to tracking, etc..., but the wake is phenomenal.
