Hey Clint
I know it's not 175 grains, but I'll definately second the idea of the 235 grain Grizzly Kodiak. I've used them with great results on a couple of trips up to The Territory, albeit on wooden shafts and Woody Weights to get my 335 grain point weight. I know mine is limited experience compared to some other bowhunters, but I've found them to be an excellent tough broadhead that doesn't break the bank. I'll definitely be using them again on buffalo if and when I get the chance.
Best
