Under IASF rules, level 6 can rewind with no twisting (no fulls, but tucks are ok). This excludes Jr. Level 6 teams. I don't think USASF has followed suit with the rules, but I could be wrong
I believe the ruling as of now is that International level 6 divisions can do them, but only at Worlds. Not during the regular season, at least in the US.
the new level changes confuse me still level 6 was formerly level 5 correct? Also i took it as the international level 5 division can now do rewinds not the regular senior levels.
