The PT-3P is considered a 3/4 CC and is a little smaller than the 4/4 PT-4 and has a smaller bell. It has piston valves where as the plain old PT3 has rotars. The PT-20P is the newsest of the series and is a 4/4 CC with piston valves. It is slightly larger than the PT-4. So ranking them in order of size from smallest to largets: PT-3(P), PT-4(P), PT-20P. As for the F's, I really don't know as much about them, but you can head over to Custom Music's site.
