I used 100 gr Muzzys for 25 years and never really had a problem. About 5 years ago, I bought a crossbow and started using Rage 2 just for kicks. They are some nasty Mofo's. Never had a problem with them opening too soon or not opening. This year I upgraded to the Rage 2+. They're even better. The problem is that they're expensive and either I lose the arrow or the blades get bent. Occasionally I'll retrieve the arrow and they'll work again if the blades aren't bent. Killed 6 deer with them this year. I'll give them a 5 star rating.
