Overall, I'm quite happy with this mount. Perhaps the only suggestion I would make if to skeletonize the mounting plate a bit to reduce some weight, but it's really not that bad.
Just got mine. I love that it folds up. I too wish it were just a tad bit lighter.
I've been thinking about drilling a bunch of holes in the plate to reduce weight. Maybe the back of the holder as well...
But I wonder if that would actually change the balance point and make it feel heavier?
