IDDdesertman- I would say Leica Duovids for sure. But there is one thing to consider when going with variables. FIELD OF VIEW is greatly dominished when compared to like powers. Duovids at 10x has 274ft. compared to 336ft. from a 10x42 Leica Ultravid. The 15x Duovid setting has 208ft. and the Swarovski 15x56 has a 231ft. I think that field of view is extremely important when glassing, especially at closer distances. Another option would be to go with the 8-12x42 Duovid. 8x fov is 351ft. 12x fov is 268ft. With these you gain some fov, lose a little bit in power and lose some weight and gain space(smaller size). Another option would be to go with a 12x50 Ultravid HD. Fov is 299ft. In the end remember this- Buy the best glass you can afford, use a tripod as much as possible and slow down when glassing. Good luck with your selection. CDN
