I still have not heard back from tethrd other than the automated email. I'll call tomorrow. I've used them a few times practicing with no problems. I'm only 150# maybe I'll just test them aittle harder at home close to the ground. By the time I get anything back it will be late season and if i send them back I just want a refund. There seems to be a lot of bad blood with teherd and members of the forum. I'm brand new to this and I already have a bad taste in mouth from the company.
