Tried them once, shot a deer twice, lost it. First shot the deer was quartering away, arrow ran along the rib cage instead of through. Second shot was broadside and I think was a little high. Shot another the next day, found it a day later. Never used them again. Been with others who'ne had the same story.
Shot a deer with a head like a Thunderhead and there will be so much bleeding it won't go far, that's the difference. G5's punch a hole, thunderheads slice and dice.
I do like the way they fly and tried them because I was setting up a bow for someone who used them. He'd lost deer to but I didn't put it together until I'd tried them.
