I hava a pair of 10x42 BX-4 Pro Guides that I just got done using for a weeklong antelope hunt. I looked at the BX-2, but the eye cups were made out of such a thick plastic type material, they just weren't comfortable on my face. Plus there was a noticable difference in the quality of the glass. The BX-4's were much clearer and had a larger sweet spot with only a very small "fuzziness" on the edges of the view. I really like them and the way they fit my face, but that is a personal prefrence to each person. Now I did upgrade to these from an older pair that I had sent in for repair, Leupold was great in helping me out in that aspect as I only had to pay a minor upgrade charge to get into the BX-4's. I also loked at the vortex in that price range, but the greenish tint threw off the view to me, however they were very comfortable to look through. I used mine all week in an AGC harness and off of my tripod, which is where I felt they really shined. I was able to spot antelope at well over a mile with no problem. For the price and Gold Ring warranty, I think that they are hard to beat. On a side note they are quite light and a joy to carry around, I never noticed the weight.
