What you say about the 7700 is so true John. Back in 2009, just before are first Poulan GTG, Steve (67Mustang) came up from NC a day early, and we had a little mini GTG. LOL Got to run his 7700 & 8500 back to back in some comparison tests. I said it on here at the time, and I still think that the 7700 is the best over all saw, of the "Big Poulans". Some how the 77cc seemed perfect in that class of Poulan saw. All of them, from 4200 to the 8500, are basically the same, just different cc. I allways thought the 4900 & 7700 were the smoothest of all, and cant really tell a difference in power with the 85cc versions. Seemed to hit the sweet spot if you will.
