so im looking at vortex scopes, and there are some pretty good deals around, and I need to stay on a budget. There are some left over Gen 1 Razors 5-20, but the Gen II pst 6-24 is still about $500 less. Is the razor that much better of a scope for an extra 500 bucks. I know about tube size and stuff. Both have 10 mil turrets, so is there that much of a difference?Thanks in advance for any advise that I can get.
