I'm using my PF-500 on top of a 10 year old Avatar 115 and boy does it sound sweet, but I'm super attracted to the look of the total Flip Top package. Is there going to be a big difference between the old Avatar cab and the PF115he? The only thing I can tell you about the Avatar is that it has an 8 ohm Eminence Kappa in it. And that it sound great. Even if I get the Flip Top, I'm keeping the Avatar for my 2nd cab.
