Results are presented from an analysis of a large sample of centrally produced mesons in the reaction pp→pslow(KS0K±π∓)pfast with 800 GeV/c protons incident on liquid hydrogen. Two resonances dominate the final state, the f1(1285), decaying into a0π, and the f1(1420), decaying into K*K. Both mesons are produced with equal amounts of |Jz|η  =  1±, and no Jz  =  0.
