So many uninformed opinions...
I ride in a wide variety of locations, gear, and conditions..the only time I move my foil is when I move my footstraps. In fact, I am using locking t-nuts on my windfoil board to assure my foil goes in exactly the same place every time. My wing board uses slingshots RTS system which also assures repeatability. Anyone who has seen the inside of my van would never conclude that "that's not a quiver"
Plates were an improvement in the early 'wild west' days of foiling when everything was different and foil performance was poor. Fortunately that is no longer the case. If you are needing to constantly move your foil position you either need to update your foil system or improve your technique.
As for Tuttle not being strong enough; what about iq foil, kite race foils, or wing race foil. All of these disciplines successfully use Tuttle boxes. While the loads that kitefoil racers produce are scary, their equipment isn't.
Yeah, plate it good for allow people to find the preferred spot for their specific foil on the board they own. And is it just tradition that keeps the PWA foil racers on tuttle? I doubt it, if the plate was stiffer or better the PWA guys would be on it. Having said that I ride plate and I would say its more about the quality of the mast overall, not the connection.
