I would agree with the drawbacks of the plate but don’t agree with Tuttle being the solution.
adjustability is way too important and in my opinion and experience the lack of adjustability can easily lead to a large loss in performance vs the gain in weight and stiffness.
The lack of adjustment is fine if you ride a board custom designed for one specific front wing, mast, fuse, rear wing, and strap setup but change any one of those and you can lose performance when on foil compared to a track (the takeoff benefit is undeniable).
I believe we can make something better instead of defaulting to a compromised standard.
