Well if anyones got bad shoulder or a bad shoulder brewing, the CTX 3030 will certainly crucify you. Even bungeeing it won`t really help because bungeeing it only helps relieve the carrying of it. Its the swinging of it that will still see your shoulder off and with 5lbs + to swing two and fro, it wouldn`t be long before the pain sets in at night. Thats why I have to use a light detector nowadays.
