Britt,
Thanks very much, that's exactly the kind of feedback I was hoping for, and I'm looking forward to your low-light observations.
I'm not in a big rush to rescope the rifle, I may try to find somewhere within driving distance to look through some of them before buying. I'm also a bit nervous about buying expensive optics mail order rather than being able to inspect them in person.
Regardless, this site is a great resource. Thanks again!
