At that amount of deflection I never saw much affect. After it starts going past that, you feel it, and then when all the way down, it really makes a difference. I originally had a momentary switch on my down, but quickly replaced it with an "all the way down" switch. I get close to 90 degrees.

Heath - Lexington, SC -----Original Message----- Far more important than whether the board has holes or not is whether it can be extended to something approaching 90?. Flying Jim Morehead's KR with it's excellent belly board was several orders of magnitude better than mine which only goes down 35 or 40 degrees.
