I'm shooting the three blade this year for the first time. They fly great and had zero tuning issues. What sold me was one of my bear hunters made a quartering away shot on a 7' blackie a couple of weeks ago....the arrow passed through and hit the leg on the opposite side, shattering it. Truly Bad to the Bone.

As for sharpness, no doubt about it......but, I would say the sharpest blades I have seen are on the G5 Strikers.
