I suggested the parallelogram mount for terrestrial viewing because they CAN be used from a reclining chair and many people prefer them just for that reason. You just sit in your recliner and you have nothing to impair your vision and you can make small adjustments up or down much easier than a regular tripod. A very comfortable way to observe and once you use one you won't go back to a normal tripod. If you are getting a 25x100 binocular you might be tempted to point it up at the night sky on a clear night and you can't beat the parallelogram mount for that.
Well, you got me there. I didn't think of that.
The problem, sometimes, with trying to provide a helpful answer is that in the process of envisioning what the OP is trying for, one tends to conjure how they would use them, missing something.
I was thinking being more mobile because that's how I would probably use them, though as you pointed out, one isn't likely to go far with any set up that includes these big bins.
