  A combined fit is presented to data on pbar-p annihilation in flight to final
states eta-pizero-pizero, pizero-pizero, eta-eta, eta-etaprime and
piminus-piplus. The emphasis lies in improving an earlier study of
eta-pizero-pizero by fitting data at nine pbar momenta simultaneously and with
parameters consistent with the two-body channels. There is evidence for all of
the I=0, C=+ q-qbar states expected in this mass range. New resonances are
reported with masses and widths M,Gamma as follows: JPC = 4^{-+} (2328+-38,
Gamma=240+-90) MeV, 1^{++} (1971+-15, 240+-45) MeV, 0^{-+} (2285+-20, 325+-30)
MeV, and 0^{-+} (2010 ^{+35}_{-60}, 270+-60) MeV. Errors on the masses and
widths of other resonances are also reduced substantially. All states lie close
to parallel straight line trajectories of excitation number v. mass squared.
