The only advantages to a double is that they store smaller and accomodate smaller IPD's. They are much harder to bring to focus from the collapsed position, the hinge tension is never the same for both hinges, so they look like the Millenium Falcon on a shallow turn unless you fiddle with them. Also I would suspect collimination could be a greater issue with two moveable attachment points as opposed to one.If you could put the ZRD HD quality and price into the following package sizes, I would buy one of each.8x32 - same as Minox BDBR7x28 or 8x28 - same as Vortex FuryTom</blockquote>
