Awsome broadheads. I shoot them out of my high speed compound. They are THE most accurate fixed blade broadheads I have ever shot. I have shot a lot of different broadheads. Most people that say they will be hard to tune out of a compound have never shot them out of a compound are only going by what they THINK will happen. They penetrate like crazy and are very durable. Being that they are 3 blades they have always left a good bloodtrail. The only issue some have is putting the initial edge on the blades. But once you get it...resharening is a snap. Use them. You will not be disapointed.
