Power,
If you need help sizing up a bear, just give me a call & I'll come right over and tell you that it's obviously too small for you, while I'm not as hard to satisfy and he'll do just fine...
I live in the Tri-Cities and have been hunting for bear for 3 years, still haven't put one in my scope...been to all the places that SHOULD have bears and some places that have been suggested to have bear, and am yet to see one in the wild, when I had a tag...
So I guess my take on this is that you're already a VERY successful bear hunter and should take your time and find the one you really want. From all that I have read, the two posts you got first are all you need to know about sizing. The legs and the ears...it's all about them parts! If you can track one, look for a 4.5" front track ofr bigger. Supposedly a 5" pad will put in into a 5 footer plus. No experience here, but I've been reading plenty.
Best of luck to ya man,
