Keith, I hear you, but if I'm riding at the level in the picture below, I don't want chop. Nor should I ride chop so that someone can wakeboard. I think it's just a matter of education and common courtesy.
We as wakesurfers, hopefully can be respectful. So like others pointed out...not doing power turns. If you're just goofing around and not riding HARD like James is in this picture...you can leave the butter for folks that need it to practice their sport - slalom and wakeboarding/skating.
Also, as surfers we need to be cognizant of how our rollers get tossed. Not only do we send rollers out along the side of the wake, but our tables are massive and we send those down the line. Be aware of folks in front of you too. It's pretty easy for everyone to find relatively smooth water.
And to everyone that is wakeboarding, if all you are doing is goofing, you don't need the butter either. I would ask that respect be given, not to treat wakesurfers with a level of prejudice or disdain, or assume that everyone that is surfing is just cruising OR for that matter that any single watersport is somehow more entitled than any other. Keith, not addressed at you.
Give respect and expect respect in return. The folks over at www.endofropegang.com
have an excellent article that talks to respect for other boaters.
