Outdoorsmans, but man you will pay for it... I used the Jim White adaptor for a long time (now the Vortex Unidaptor) and I liked that a lot. Once I bought swaros, I wanted something that would lock in and be easy to put take on/off the tripod. The outdoorsmans fit the bill, but the price is retarded for a couple of pieces of machined aluminum.

That's the biggest reason I went with the Outdoorsman. I felt it wasn't easier to use especially with cold hands.I've had some difficulty popping the binos off my Field Optics adapter. Seems like a tight fit. Probably something that a smudge of lithium grease will solve. Like it when classing tho.
If you go with the Outdoorsmans you'll need an adapter plate to fit the Promaster tripod. I think the tripod might come with one already but if not you can buy one pretty cheap/easily. The Outdoorsmans only mount to Outdoorsman tripod heads without an adapter plate as far as I'm aware.
