OK, assumptions can be wrong. The Porro design produces a better image at a particular price level than a roof. So your idea isn't far off. The Legend porro will likely be better than the Excursion. If I was looking for an inexpensive porro with good usable optics, I'd look in two ways. First is the Leupold Yosemite. These only cost about $100, and the optics are very good. Next level up look to the Leupold Green Ring full size porro's. The Cascade porro is discontinued, but still available. The Mesa is still in the catalog, and there is the brand new Rogue. Those have a really nice image. They are a little more expensive than the Legend, and smaller if that is a concern. But the Legend gets consistently good reviews,and it is a darned nice glass for the price, so yeah, personally I'd get the Legend if the Leupold didn't work for me. I happen to prefer the image of the Leupolds, but the Legend has a wider field.
