 note = {Tumbling complementarity is studied in chiral preon models based on the metacolor group E6. By considering the breaking of E6 into each maximal little group in the Higgs phase, several models are found that are in accord with complementarity. Three families of massless fermions (on the metacolor scale) can be obtained, but so far we have been unable to identify an E6 × SU(N) preon model supported by complementarity that correctly predicts the quantum numbers of ordinary quarks and leptons.},
