Deke, I appreciate your comments and I think we're getting to a core issue. When I was Army test flying helicopters, we always started balancing a rotor system by first hovering, putting grams of lead weights on or off the rotor first to "balance" it at a hover. Then we "track' the blades by fixing the "gap" bringing the together by adjusting the Pitch Control Links, before we even start to fly it. This could take a day but was an important step. Getting things to straighten out at a hover BEFORE even flying was an essential first step. If we didn't spend the time on the ground first, it would NEVER be corrected by flying it in the air. This brings me to my point, Blades in the air or blades on the ice, you have pro shops that are throwing you into the air before knowing anything about how you feel on the ice. I start with you standing on your skates with a single radius and tell me WHAT you feel. Where is your center of gravity (GC). Then we slowly work through what you're saying by trying single or combination radius first. Correct yourself first by going back to a single radius. Find your CG, then start adjustments by moving a pivot point, fore or aft. Now, more acceleration, try a combo 10/13 with "YOUR" pivot point, we continue to work like this until the skater locks in something they like. We work simply and slowly at first, then go more complex and quicker downstream. If you're having problems with your blades, have the neutralize back to a simple profile and work outwards from there. I work with D1 hockey players, juniors, high school et. I use this method and give them a "testing" profile which is pre-profiled so costs for doing this are low. Once the skater is locked in, that's when they get charged for the profile. Same cost as if you sent them in the mail to me.
