If you get a chance to go and handle a few tripods, camera shop, hunting store, etc…. I would suggest that you look at trigger style heads as well. For only glassing ball heads are likely not the best or easiest, Fluid pan heads are really nice but not as quick to center view, the trigger heads are really quick to center on your view and solid. Since you are not planning to pack this in weight is not such a concern, so that would allow you to find a cheaper tripod.
Do you already have your SS or RFB’s, and your bino attachment? Those things could affect which option works best for you.
