I've used the G5 Montec 100gr. for 5-6 years and have never had an arrow stop at a deer. Always stuck in something beyond the other side. I had a really jumpy whitetail doe jump the string on me once and spined her. It destroyed her backbone(looked like a bullet had hit it) and buried in the ground on the other side. Ran it on a stone and used it again. You'll never get them super razor sharp but I've never seen anything short of a tree stop them either. PLUS they always fly as true as my fieldpoints which makes me happy and confident.
