Pats Peak uses HDPE and it works pretty well for the most part but it does scratch and can be slow when it gets dry but overall for personal use it would probably suit you just fine.
Waterville Valley uses UHMW Poly which is a little step up from HDPE, its stronger so it doesnt break as easy, has a lower rate of friction so it slides better, and has a higher density so it wont scratch as easily. But it will cost about $30-$50 more depending on the thickness.
Loon uses Lexan which is a polycarbonate. It's not as strong as UHMW but close, very dense so it takes a lot to scratch it, but it doesn't slide as well as UHMW but still very good. The upside of lexan is you can get it in a variety of colors including clear. But Lexan will run even more than the UHMW and i think personaly it'd be a waste of money for personal use. But it's you're call.
