I'd also opt for the 26 inch barrel. 25-06 is overbore (almost magnum) and you'll get a velocity gain over the 26 (not sure how much)
Weight might be a factor, too. I have a 27 inch VVCG barrel (0.800 muzzle diameter) with the VVCG steel base with a 4.5-14 Burris scope.
I don't have a total weight on the whole rig, though. It isn't bad to carry to a stand and back, but I surely wouldn't want to stillhunt with it all day.
