I have friends that have used them and although they look wicked, might not be the best for the everyday hunter for a few reasons... First off depending on model they can be a pain to sharpen! Second they are a short broadhead and have a big cut which could cut down penetration unless you pull heavy poundage! He and another friend each got an elk in MT two years ago with almost the same equipment, except broadheads! The Simmons Shark only got one lung, but the elk was recovered, the other elk was double lunged and went down in sight(MagnusII)!
