My buddy rode the new strap and he felt it was a completely different feel. He thought it pulled the boot better and that the bindings felt more responsive.
I don't think they redesigned the power strap but they did add the new ratchets which are even better than the last redesign on the ratchets. They are super smooth and much easier to use. The larger release tab is awesome and even the bigger ratchet tab.
I'm sure others will chime in its only 8am on a Sunday most people may still be sauced from last night....
