I thought i'd just quickly share my experience of using my Slingshot Golf (wakeboard) bag recently.
Got through the ticket counter without even a wink. Super easy, no questions asked, no fees (beside the $15 for ANY first checked bag)
I realize that this was just one experience with one airline (Mid West Airline) and probably cant be used to represent all airlines, but i thought there might be someone who might like to know it works, even in today's world of airlines and economy.

I am sure someone is gona ask where i went (Iowa and Missouri) that i took my board... actually i took a kneeboard FOR SLEDING ON THE SNOW (my father-in-law did not have any sleds, i think kneeboards make awesome sleds, i don't own a snowboard, and we did not have time or money to rent.) The kneeboard was almost too wide to fit in the bag and made a nice bulge in the middle, still, got through the airlines no problem.
i do plan to use it for my wakeboard for a trip to florida planned this summer though!

if anyone is still lookin' for a bag, go for one disguised as a golf bag. you never know when you might use it, even if it is not for wake gear. ;)
I only know of Slingshot and BestKiteboarding and LF that sell these type of bags. I have only seen the Slingshot one, which wont fit boards any larger than 142 i think. I have a 142 recoil and it seems the bag was made for it, just barely fits in. The dimmensions of the Best one sounds like it is HUGE, but it is also pretty expensive. In short, make sure you know the dimmensions before getting one if you ride big boards
here is a link to the bestkiteboard one. you can google the others
