My first hunt of my return to bowhunting after a long absence will be for black bear. I shoot a reflex grizzly 60-70lb, 27"DL. Right now i only have red head carbon fury 6075 (11gpi). What do you consider a good arrow/broadhead combo for those overweight potentially nasty black bears? What total arrow weight would you want? I think I have been already talked out of mechanicals by some experienced bear and moose hunters, at this point the montec G5 looks good. Would you go to 125 or stick to 100 grs. ?
