Well, not these tabs. They affect size and shape dramatically. I have been on every major system out there, and pretty much every newer boat without a system.
I haven't first hand seen the new moomba 'cattle' gate or the supra swell, but have been on their 2014 boats.
Played with the Mastercraft Gen2 tabs yesterday on an X-30, and I am very impressed. Solid engineering and design. Probably the best equal weight system I have experienced. Definitely, top 3 of any system, IMHO. A truly solid mixture of displacement and standing wave energy with easy shaping mods, and effortless side to side transition in seconds.
It is a great time for surf boats. Some really solid additive systems out there, as well as some really great hulls that can produce some great wakes.
