Please stop making players start from weave 41, if they have already reached 120 or 160.
No one who has reached the high weaves is going to have fun to replay the lower weaves since they just roflstomp through it. Replaying the final 40 weaves is fine, but doing it 3 (4) times every season only for getting the highest frames is annoying.
It should be possible to earn low ranked weave frames by completing the high ranked frame challenge.
Completing all Helmgart maps with one career on Legend gives you the rewards from difficulties below. This should also apply weave frames.
