i have a ho sports striker knee board. it is a good ride but not great. it seems to not catch a edge easy so its very hard to charge the wake as i would like to. i am losing out, i feel on speed and height. i was wondering if anyone has this problem and was thinking about putting wake board fins on it to try but figured i would ask before i drill holes in a random place on my new 275.00 board? also is there any instructional videos for knee boarding on how to do more advanced tricks? i would like to learn back flips and barrel rolls by this method instead of just trying it. i attempt barrel rolls now but cant rotate fast enough to make it all the way around. i land either totally upside down to 3/4 of the way just cant get the rest of the way around.
