Are those the 2013 ON3Ps?
edit
OK, I'll make a real post about it. I heard about these maybe 2 or 3 years ago when they first came out. I wasn't sure what to think. At the time, I said it seemed pretty dumb and inefficient to me. I also said that's probably what people said about twin tip alpine skis around 15 years ago, and look how far it's come.
The biggest downfall that I see is it's so much harder to ollie on them. being able to ollie is a big part of wakeboarding. Again, probably the same with snow twins.
As SB said, cable parks have been around for a longg time. I'm sure the carbon footprint is much less than with a boat. Think about it... every time you fall behind a boat, they have to turn around, pick you up, start up again. The acceleration requires a ton of fuel. Most true wakeboard boats have wedges/ballast tanks to make the wake bigger. More weight = more fuel. Not to mention they usually have big v8's in them (somewhere around a 5.0L).
My take is who cares if others think it's cool. If you're having a good time, keep doing it!
Wakeboarding is lots of fun. I did it a bit yesterday. Right after sailing and paddling some whitewater
. I need a GoPro/waterproof camera so I can feed the summertime stoke machine.
