Group Buy for '04 Flight Control Clips

[BASC]

I have just arranged to trade in my trusty very reliable 92SN in for a newish 02SN which has a Flight Control Tower fitted. I wasn't looking for one with a tower but it was included so I will have to break with tradition and take up wakeboarding. (more expense and porbably divorce will follow!!)
Anyway my question, what are these 'Flight Control clips' that you guys are talking about, and what are they used for?

Fancy name for board racks.
I was quoted $582 in silver from Mid Ohio.

Just an FYI, Mid Ohio told me that "sliver" is just the color of the paint. If you want the ones with the metal showing, brushed, polished or whatever you call it, they're about $617.
