I owned a pair of BNs, which were very much like the BAs. I thought they were an excellent pair of binoculars. However, I also thought they were heavy, and for that reason I sold them to buy a pair of Leica Ultravids, which I didn't think were very well made. so I traded for zeiss victory HDs, which I didn't think were very clear.
Bottom line. get a pair of used Swarovski ELs. You will be happy you did.
