Can any one give me any technical data on the easton epic carbon 400? I was just given 2 dozen and want to know if they are compatible with my bow. My draw length is 29" at 70lbs. single cam bow with an IBO of 302. If you know anything about this arrow or have shot them in your bow please tell me about their performance and penetration abilities. These are not the new epic 400 st, just regular carbon epic 400's. Thanx in advance
