LAST EDITED ON Jul-07-08 AT 09:45PM (MST)[p]I would go with the Vortex adapter. If you dont already have this, you will also need a quick disconnect system to quickly remove and add the binos to your tripod. I went with the bogen RC2 adapter and plates. They are awesome. My set-up is a medium outdoorsmans tripod, swarovski 15x56 and spotter. Each adapter is around $25.00 and plates are only about $10.00. I have a plate for each of my optics, camcorder, gun rest, pistol grip head and fluid head. They quick disconnect in a snap, are pretty lightweight, rock solid, very sturdy and have a safety lock. I love them Good luck on your decision.
