Judman,
No, the "minimal" chance of a grizzly encounter doesn't trump all else.
I have hunted (and fished) a lot around grizzlies from Montana to Alaska, and aside from being bluff-charged more than once, had one try to take a freshly-killed moose away from me in British Columbia. (Have also taken one grizzly, in Alaska.)
One factor here in Montana is that it's been almost 30 years since we had a hunting season, and many bears have lost any fear around people--one reason we generally have at least one mauling a year, often fatal. Last fall I had a mule deer doe tag in an area where there was a chance of encountering a grizzly, so used a little more gun than I would have otherwise, my NULA .30-06 with 175-grain Barnes LRX's. It worked fine on the doe, with typical minimal meat damage.
