Outdoorsman hands down. Light, compact, unobtrusive, well made with no parts that can wear out. Mount up solid, I've carried my 15s on the tripod over my shoulder for 1000s of miles and never had a problem with the mount. They make studs for old style leicas and can install studs on ELs. They even make barrel clamp style mounts for 2 gen geovids. The only bino that I can think of that can't use the system are the newer Leica HD-B double hinge style geovids and they might have something figured out by now.
