Trying to find 70's kung fu movie.
I am trying to find a kung fu movie possible in the 70's vintage period. This movies plot involves a young student of the Tiger style that has not mastered it due to his Masters murder. He then has to avenge his master but must combine Crane style to 'fill in the gaps'. One of the training apparatus is a wing chun dummy of sorts that has passages for marbles to fall through that he must catch as he works the dummy. Of course in the beginning he can't catch the marbles but when he is ready to avenge his masters death he can now catch them proving he is ready.
