I was in a similar situation to you hunting1. I just bought two Tikka Superlites and have no regrets at all. They are about 7lb rigs. Check out my initial range reports if you haven't already. Like many have said though, if money is not a big concern, the A7 is probably the better rifle and should hold its value better than the Tikka. I too was seriously considering a Forbes, but was hesitant because they are so new. That said, after a year or so, and any bugs, if any, are worked out, I would really like to get a 20B. Check out pics of shortactionsmokers Forbes 20B...sweet looking rig. All the initial Forbes reports I've seen so far seem to be good.
Just my 2 cents, but from what I've read on here, I would not take a chance on the Montana unless it was a known shooter.
