i approve the use of counter balance, but i dissaprove the use of hydraulic dampeners i tried to use carr-mcmaster dampeners in a design i had 5 years ago, but it would be server to use on the wrists. always think egronomics.
he uses an aluminum clamp and a derlin rod, my collective uses derlin clamps and an aluminum rod (1" diameter to be exact- the bigger the better for increased friction area) the answer i got from this thread was derlin collar clamps.. enco.com is a good place to get them
