Kinda-sorta mulling around the idea of getting a new scope before this coming deer season, especially for my NV hunt. I like the looks of the Kowa TSN-663. Anybody here used one? Opinions? Also, does anyone happen to know how big the Kowa 20-60x eyepiece lenses are? Its hard to tell from the factory photos, but I want something with a good sized "rear" lense.
