Alba: I have hockey skates too. I don't love them, and occasionally fall backwards. Of course they have much smaller rocker in front and back than 7'. I also have some extremely old MK Dance blades that had 7' rockers - but so much metal is gone that the toe picks are all messed up - trimming them changes the forward/back toe pick positions.
Others: The coaches I am currently taking adult group lessons from (one room schoolhouse style - but classes are small so they take turns teaching each student) are trying to get me to abandon the old Russian style ice dance style I learned, which emphasized:
1. Lean and weight forwards while skating forwards, back while skating back. Was never good for 3 turns, or other 1 foot turns. New coaches say to do the opposite.
2. Not touching toe pick. But current coaches say it may help me lean back after forward turns to touch the toe pick, then push back. (I don't know if they only teach that to people who have trouble checking turns.)
3. Counter-rotate upper and lower bodies. Current coaches say this is very bad - that I should turn from the waist, not below - especially when not doing ice dance - but I was always told counter-rotation is mostly not typical of American Ice Dancers. It is probably one of several reasons I never managed to keep an ice dance partner.
4. Very low body position (knees bent to almost sitting position while stroking). I'm simply not strong enough to do this now - which means more of my body weight is forwards than it used to be.
My current coaches say I should start forward 3 turns in T position (free foot instep touching skating foot heel), then push it back during turn to absorb angular momentum. Also, I am using head wrong. And since they are mostly talking freestyle, I can use my arms to create and absorb angular momentum, as long as they look well controlled (not wildly swinging). And they are urging me to bend my knees before the turn, rise up during the turn, and rebend at the end. I think I learned that before, but somehow forgot.
These changes are helping somewhat. Though I'm still skidding a bit, and my exit arc has a somewhat smaller radius of curvature than my entry arc. I should probably give them more of a chance to work before changing my blades. Especially since they say I should only roll back to mid-blade, not the tail.
I did add a little height to the back of my insoles. Makes it marginally easier to put my weight on my heels.
