I have taken two deer with the rage 2 blade so far and got complete penetration on both and never had one open in flight to my knowledge. So far so good. I get a kick out of the G5 commercial with T-Bone. Always wondered why G5 didn't compare their 3 blade head with the Rage 3 blade instead of the 2 blade. Apparently they think no one will notice.
You know, I just saw that commercial the other day and thought the exact same thing. I actually just got some rage 3 blades in the mail the other day, but after examining them compared to the 2 blade, I feel like the 3 blades are are not as secure in terms of opening in flight. I think that because of the angle they are sitting at, they don't tuck in onto the rubber o-ring as well as on the 2 blades.
