It's more a matter of bag material. Vinyl is not as flexible as polyurethane, but polyurethane is pretty flexible. I've seen video of one of the high-tech brand-name polyurethanes conforming to a softball with barely a wrinkle. In our shop we used polyurethane, but we never did any fancy stuff, usually flat veneered panels and curves. Occasional laminating of forms, but nothing as complex as a softball... In art school we had frames that could conform to amazing shapes, but I never paid much attention to them. My interest is more in wetout with the heavy CF cloths. They seem to be difficult to get full saturation in a hand layup. It's hard to tell if you've got the whole thing wet out. I'm sure vacuuming would solve that problem.
