there is a review of the Leica Ult 8x20 v Nikon HGL 8x20 v Opticron Tagia 8x25 v Swarosvski 8x20 v Zeiss 8x20 entitled corrected review from 2006 number 1
Great review. Thank you for the link. I now have the desire to give the Opticron Taigas a try. They definitely sound like they faired quite well with the more expensive roofs.
