WWMark............ well said.
Bill..... not sure what you mean by "Bump"?
BT has always been a heady designer, but I bet he will attest to how few really proressive surfers would immediately jump on a system like this, as WWMark cites surfers being slow to explore potential.
A case in point is tri vs. quad....... yes, there are more McKee influenced five fin setups starting to appear in the mainstream.......... Rusty, C.I., Lost.......... the big boys, and this acceptance allows others to follow suit. Forget that it was smaller manufacturers that more readily explore things such as what is being discussed here. The truth of the matter is until it gets exposed with the 'big boys' with their corporate advertising budgets and paid pro surfers, nothing moves into widespread acceptance much less use.
Distribution is a huge challenge for anyone trying to promote a heady, well conceived idea. I've asked for this system more than once, emailed, got a response about being contacted by their rep out of So. Cal........ then nothing.
Quite honestly, the ability to vary your toe in, cant, etc. is HUGE. BT will tell you that. The good shaper designers have very specific toe ins and cants that they adhere to for various designs they make. With quads this is even more readily apparent than tri fins as the choice of flat, eliptical or two side foils makes a significant difference in how they perform.
Now add the ability to do more from a system like this and you can explore and produce anything that could range from magic to catastrophic.
But going back to WWM's remark...... most surfers by and large do not, and will not experiment with a system like this even when their shaper tells them that it is a great feature worth trying.
The main problems are:
Lack of Distribution & Marketing
Lack of production set up to offer them... (new stuff can represent new tooling... not good in soft economies)
Unwillingness to subject one's self to peer pressure........... tried and true is s--a-f-e (can also be stagnant).
Swaylockians often seek adventure & sometimes are a bit crazy while the rest of the surfing world just shuffles along.
