Well, my first year using the Rage 2 blade heads. I've been fortuante to harvest two turkeys and on nice buck just yesterday with the heads. The size holes were amazing, and I had no difficulty recovering any game. If there is any down side I see with them it would be the price and lack of overall penetration. I shoot a Matthews Outback at 63lbs with Gold tips. I managed to get about 11 inches of penetration which with good shot placement should be good enough, however; I miss not being able to get a complete pass through.
