Not sure about that. I can't get a surfable wave on the starboard side (although I haven't spent tons of time trying....) I think his logic is backwards there.

As far as boards -- I can't even begin to open that can of worms. Here's my recomendation -- get everyone that you can hooked on the sport of wakesurfing and then encourage them to buy boards. Or buy up any used boards that you can find. Or start making/shaping boards. You'll be amazed how different every board rides. Once you start trying to spin or get air, they make a HUGE difference.
