Rocket Ultimate steel 100's & Ultimate Titanium 100's.
Both are fixed blades and very accurate. Very strong as well. The Ultimate steel 100 is responsible for the new SCI record bookGrizzly. That seems like a pretty tough animal to take down. Go to cabela's web-site and click on thearchery link on the left hand side the click whatever broadheads you are interested in (fixed blade / mechanical)and you can look and a lot of old and new ones on the market to at least get an idea of what is out there to choose from. I know for sure that Montec, Rocket, NAP, Muzzy, Tight-Point, and lots of others are up there with pictures. Good luck!
