Really good review. Thank you.
This is a late reply. Time in the field will be a truer test, however I bought one of these for my bow last fall. During the winter I threw it in the snow when I walked down to retrieve my arrows. It was not super cold out but I buried it for a few minutes. I picked up the bow, shook out the excess snow and it shot fine. I see the potential for freezing up in really harsh conditions.
It performs as advertised IMO. And I did some moving about with the arrow captured and it retained it well.
I agree with the use of mole skin to substitute for the factory felt.
Cheers
