Overall i like the 5.9 LBS, the aesthetics of the new bolt and the possibility that it might be less grabby than the fluting of the Lightweight hunter, and Ultralites i have. I don't know anything about the stock, but it looks like it will be more rigid than the current stocks, and that is a good thing. The Proof Carbon barrels are just a winner. I have them on my 3 Ultralites, my Proof Elevation and two custom rifles. They are just as accurate as my Shilen Select Match barrels and half of the weight.
BUT... That kind of pricing is really insane. I paid less than that MSRP by hundreds for my Proof Research Elevation, and it has the same Proof Research Carbon Barrels, and a carbon fiber stock, and a Zermat Origin action.
