Looks like Kit has a Broadcast. The fins on the boardcast are maybe 3 to 4 inches. Kit the next time I ride I plan to remove the center fin on my Broadcast to see if the board loosens up any.
I also have a Trick Boardz Mojo. The Mojo is a symmetrical board. I'm going to take off one of the fins so when I start I can chose to start with a fin in the back or not. The Mojo is already pretty lose compared to a Broadcast, it will be interesting to see how it rides with out a fin.
