FWIW the guy from HockeyTutorial says that he likes the 70K more than he likes his VH skates (in a recent video where he is unboxing stuff at his HQ). I have never heard him get so excited over a retail skate (previous retail that he seemed to like best was Mako). So, I would not be surprised if thee significant type changes that you reference, were made (but the guy doing the promo video may not have wanted to talk over the "average consumer's" head, and thus he may have failed to mention these nuances that only we would appreciate).
