I use a Prior MFR 165 Quad Glass with Rome Targa bindings. The Ride is awesome, super damp yet ultra responsive. However, the base is too thin and soft, and will gouge if you go near a rock. It is also starting to delam in the center of the base, and Prior insists that it is an "Insert Placement Guide" that shows up on some of their baords, and will not warranty it. This was my first and last Prior snowboard. They do not stand behind their products.
Before this I rode a Salomon Fastback 160 w/Salomon SP4 bindings for years, and hit many rocks/stumps etc. Not a single one got through the base. However, the ride was a bit weird, hard to describe. It was tougher to turn than the 165 I am riding now, even though it was super stable at speed.
Once the Prior is done, which wil be soon at the rate it is deteriorating, I'll be looking at a Never Summer, Salomon Burner, Venture, or something from Mervin if they decide to make a good freeride board.
The Never Summer SL-R is the best all mountain board I have been on... Ever.
Buy it... Ride it... Love it...
