  A detailed and systematic ARPES investigation of the doping-dependence of the
normal state Fermi surface (FS) of modulation-free Bi(Pb)2212 is presented. The
FS does not change in topology away from hole-like at any stage. The FS area
does not follow the usual curve describing Tc vs x for the hole doped cuprates,
but is down-shifted in doping by ca. 0.05 holes per Cu site, indicating the
consequences of a significant bilayer splitting of the FS across the whole
doping range. The strong k-dependence of the FS width is shown to be doping
independent. The relative strength of the shadow FS has a doping dependence
mirroring that of Tc.
