Here's the link to the buckle I use:

It's the one papasquirrel recommends. I love it. It's tiny, weighs practically nothing, but is rated for 1200 lbs. If you can break it camming it over, you're a better man than me. I've never had it come undone. There's not a lot to bump with your boot, and even if you did it locks down pretty tight.
I use a poly strap and bow up on that buckle like I mean bizness. Red says loosen it a little before you cam it, but I don't. I force that bad boy over. I walk my steps down at the start of the hunt to snug them up. They very rarely make noise. I won't say never, but it's no noisier than anything else I've tried.
I'm not out anything if you use a ratchet. It may work great for you. But I love me some OCB. If you want to give it a shot, this is the one to use.
