I have the original PE's (2 seasons ago) just freshened them up with a little paint job,
They really are a sweet ski on anything other than sheer ice, I mean last year i also skiied some Sx 11's And obvoiusly they didnt compare,
As for the PE they pretty much rip on the groomers, I dont know about the new 85mm waist though, but they do carry the same side cut and the extra girth stiffened them up slightly so the hardpact still shouldnt be a problem.
Other thant he old top sheet they seem to be pretty much bomb proof, so the new P-tex top sheet should make this ski last a while unless you really get on it in the park.
Let me know if you need any more specifics
