I have an older, fairly heavy Vortex Skyline ED 20-60x80 (Angled) @ just under 6lbs.

Had it for years, the glass is clear and serves my purposes out to 500 or so yards. I'm looking for a lower height/profile tripod for use on a bench or occasionally shooting prone. The few I've tried have been too lightweight or unsteady for easy, reliable repositioning w/o wobbling all over the place. What are common mid-price options folks are using these days?
