I know lots of guys who can draw 80 lbs easier than I can draw 60, and I can draw 60 very easily. There are some out there who are hunting whitetails with 60 and 70 lb bows and a grizzly must be about 5 times larger. I know if I was hunting brown bears, I'd be using the heaviest draw I could handle without problems and the heaviest arrow I could put together. By all means, if you can easily draw it, then get the heavier draw weight bow.

I doubt many shops stock the hevier draw weights, so you'll have to trust the brand or try shooting the equivalent 70 lb model.
