For just general purposes don't overlook the Nikon Monarch series. Very fine glass for the prices. If I didn't have several sets of Zeiss Classics in 10x40's and 8x30's, I'd be using the Nikon Pro Staff 7 8x30 or next step up Monarch 7 8x30.
As you stated, your PH will be responsible for the "judging" so your 10x are more than enough. May want to look at 8x for additional sets. 8x will give a wider field of view and if you're hunting in the brushier areas, the lower magnification can make it easier to define brush from horn and hide.
