Eh, poop piles can be misleading. I think it has more to do with what they're eating than the size of the bear. I've seen smaller bears leave some huge piles and vice versa. First bear I ever killed was leaving some massive coke-can diameter piles, we thought oh boy we have a 300+ here. Finally killed him and he was about 190-210ish, this was before trail cams and I wouldn't have believed it was the same bear if he hadn't relieved himself one last time at the sight of the kill. To this day some of the biggest turds I've seen out of a black bear. But by all means that could be a good bear and I say go for it!
