I'm in the market for a quality tripod. Want to keep tripod and head combo under 500. This will be used for glassing from landings at pickup as well as backpacking so weight is a concern. I've been eyeing the Silk Pro CF-734 with video head. My concern is stability should I step it up to the CF-834? Which is half a pound heavier but will hold 4lbs more. Any other suggestions? This will be used with a Kowa TSN-774.
