Yep, the Summit is a quality scope all the way through. But there are real reasons I wouldn't run one on all my big game rifles:
1) Can't afford $1500 to scope every dang rifle. (Now, if I only owned 2-3 big game rifles, like a rational human being might, then...?)
2) They're a little big and heavy for some of my rifles.
3) Still haven't failed to kill any animal I've shot at with a fixed scope--or at least, the failure wasn't due to being unable to aim with the scope. That would also include quite a few variable scopes set on 6x and left there, my SOP.
Now, on a couple of rifles I have decided on a little more magnification. One is my custom 6.5-06, which has a fixed 10x, since it's a specialized rifle for long-range.
JB: I agree.......for me the Summit is for when I need/want a bit "more".Completely agree on the cost thing too.
