What kind would you recommend...im planning on going next fall but would like to get a good idea now of what i should shoot. I shoot muzzy 125 4 blades now.....i figure that would probably be alright but mine as well ask a group who may already have a clue.

nothing wrong with the muzzy. Stay away from mechanicals on bears, they have tough hides and big bones, you need a stout fixed blade broadhead.
