Freestyle Jet skiing? I think that would be pretty cool. Potentially X-Games worthy to me.
ILLinoisanceI'd vote no on making it an X-Games sport until the sport gets a little more established and has competitors able to do more than a few different tricks.
MinggIf and when the sport becomes more developed I think it would be cool to have like a best trick comp like they do with snowmobiling and motoX. Like I said in the OP I think it could potentially be cool one day. Maybe not in the X-Games, but I think the sport definitely could become big.
