Course you could buy a pre-flattened poly with Gosen PolyMaster. But it wouldn't play "flat", would it?
it depends on the poly. some polys leave more 'tire marks' than other. I tried TF Red Code 16 and the crosses were so flat that it did look alot like a ribbon after ~15 hrs of hitting. after 20 hrs of hitting w/ Iontec, the crosses are no longer round, but they're not nearly as ribbon like as TF RC.
when i've used OGSM and NVy for crosses, they end up pretty flat after 6-10 hrs depending on the string pattern of the racquet.
