Also seeking light weight and size, I just bought a March 2.5x25x52. I'm very satisfied with this scope. Optical quality is one of the best I've seen, and, tracking, and weight/size is superb. I have had very good success with the Huskemaw 5x20x50 for several years which is similar in weight and size to the March and the cost is much less. I'm very partial to a fast ratio parallax/focus knob for hunting, which the March and Huskemaw have in common. Optical quality and tracking of the Huskemaw is comparable to my NF NXS's. Looked at the Swaros, but also had some uncertainty about tracking and durability.
