It seems to me that having two mounting points potentially creates a pivot point on the board. I understand the binding is flat against the top of the board, but under heavy stress, when rocking back and forth, it seems that having at least three mounting points would do more to prevent any movement.
On the other hand, it doesnt ever seem to be an issue with wakeboards. Although Im not sure they take nearly the pressures/load of a snowboard.
I wonder if this will become a more common system industry-wide, or has Burton set this up to remain proprietary? Lack of options is too limiting for me. I love my '08 Burton Supermodel, and was disappointed that it was only available as ICS in 2009.
