True compact and lightweight binoculars are at best a compromise.
Probably the best binoculars, IMO, for a hunter are fully multi-coated roof prism binoculars in the 8x40 or 8x42 range. They will run in the 30oz. to 40oz. range in weight, but with a binocular harness in lieu of the provided neck strap, they become almost non-existent.
I find 10x to be hard to stabilize while glassing without a solid rest. The 8x binos don't, for whatever reason, seem to be as critical when used unsupported and you get the same amount of light gathering performance from 40mm lenses than 50mm lenses you'd need with the 10x binos.
Now, you also have to keep in mind that I'm hunting woodlands and clear cuts, not vast open expanses of the west. If I were hunting in the west, I would probably get the 10x and a tripod.
A good book article to read, if you are interested in doing a little bit of research before you buy, is here http://www.24hourcampfire.com/binoculars.html
the author has also written a book about binoculars, rifle scopes and spotting scopes that you can get at amazon, barnes and noble, etc. I my opinion this is where you will want to start before spending any big amounts of money on optics.
