Yeah but they achieve these speeds by using a dangerously light weight arrow. A bowtec or mathews would shoot just as fast or faster with that light of an arrow. Here is my impression of what will eventually happen to the people who keep shooting HCA bows with arrows that light.

EMT: "Knights ambulance to Mercy General ER.. do you read?"

ER Nurse: "We read you knights"

EMT: "We are in route to your facility with a 33 year old white male who has what appears to be an idler wheel from a compound bow lodged in his left nostril. Subjects vital signs are as follows, heart rate 133, blood pressure 200 over 110, respirations 34 per minute. Subject appears dazed, has a blank expressionless stare and keeps mumbling the word BOOM every 30 seconds. Subject also seems to have lost all control over his bowels and bladder as well. ETA to your facility 5 minutes."

ER Nurse: "10-4 Knights. Jesus, not another HCA speed freak. Thats the third one this week."
