I've used the Vortex SUMMIT SS-P ..... specs say 2 lbs, but I think it's a little heavier. I Might look into trying to lighten it up.... I don't need the extended height. All in all though, it's been solid for sitting and glassing with a Swaro ATS 80 HD ... Just got an ATM 65 HD, so will be trying that with it next.
