I'm in the process of doing daily feebay searches for P/P2 or C carriers, some sellers list the carriers as 8x10, some do not.

Could some one tell me if there is a difference between an 8x10 carrier and the other smaller (4x5, 5x7) carriers? From the little research I've done the 8x10 carrier is suppose to be beefier. Is there a way to tell the 8x10 from the smaller carriers

I asked this earlier in the thread but did not read an answer regarding the above question.
