James can spin 3's pretty effortlessly on any board and fin set up...but he's not like us mortals.
This is an experiment we did with a bullet and James was able to rotate that pretty easily. I think those are 438's and a 3.75" trailer.
The revert is an issue...on the Walzer, those rail fins grab with the board revert. Maybe relocating the entire fin cluster inboard a bit?
