I have a quad setup that has a bit too much grab. If i want to loosen it up is it reducing the front, the rear or both. I cant seem to find a website with a definite answer. Also is the a rule in design like split keel vs standard? I dont have a ton of experience with quads. They either seem to be fast and loose or too grabby. I do understand how the fin box placement of the rears effect the performance.
