I haven't found anything I like better for heads than the Outdoorsmans system. Their tripods are great too. My current favorite set up is the Promaster 525 tripod with the Outdoorsmans pan head. Their pan head is the best I've used for grid glassing an area, while still being easy to unlock to freely track an animal or glass the likely spots. I like that this head and the adapters work on either my tripod or my window mount. It's really quick and simple to use either without unscrewing anything from my optics. The Outdoorsmans bino adapters are great too and their rifle rest is nice for shots where prone over my pack isn't an option
I use the Promaster tripod instead of the Outdoorsmans primarily because of the height I get for the packed size and weight. Its not quite tall enough to be ideal for me to use standing, but it works glassing or shooting. It also has a leg that unscrews that can be nice as a trekking pole on a pack-out or used as another upright to hold a tarp in place waiting out a rain or getting out of the sun. I much prefer to use standard trekking poles walking with a heavy pack, but I don't always carry them and this is a lot better than nothing. I feel like it's a multi-purpose item that justifies a couple ounces over the lightest tripods and heads on the market.
The whole system lets me pack a tripod and head that work perfect for sitting behind with my 15x binos glassing, but that I can also glass from standing. It's also a shooting platform that is much steadier than a single yoke supporting my rifle for longer shots when I can't get prone. Add to that it has the removable leg I can use for a few things and it lets me do more while packing less.
