I have a stone age Scot which does not have a bow flotation bag. I’m going to be buying one, but I’m wondering I should get the extra protective cover as well. In looking at the Flying Scot web site, I see that the bag costs about $100 while the protective cover adds another $100 or so. Unfortunately there is no description of what the cover is comprised of. Does the protective cover provide enough protection to the bag to be worth the extra money?
