Well, Quick, here's my opinion, may not be worth much. I have an Elite 3200 in a 3-9x, nothing special, just a standard sporter scope. I think that it rates somewhere in the range between the VX Iand VX II, maybe closer to the VX I. I have a Fullfield (the original, not the II) and I don't really like it. Granted it's a little lower power than what you're talking about (2-7x). I has proven to be pretty durable, as I have it on my Whelen, and that thing does have a decent amount of recoil. Based on where the adjustment turrets are located, if I wanted to move it back any, I couldn't do it. And I think the Leupys are a bit more clear. No experience with the others.
