How about that...it's on the same page in the hardcover edition, too! :eek:
I haven't tried a hair-on-the-inside quiver before, but it sounds as though the arrow cup would be a pain to use in such a case. I would be apt to doscern the differences in my arrows (blunt or broadhead) by different cap dips or fletching, etc. Just grab the back ends of the whole sheaf if the quiver covers the nocks, and pull them up into view. When roving with a plains quiver, I just pull the mouth of the quiver toward my eyeballs and pluck the nock I want.
If you are hunting deer, and wish to remain stealthy while sneaking an arrow out, I would suggest that all the arrows in your quiver should be as alike as possible. You wouldn't want to be fooling with an arrow cup at that time anyway.
Just some armchair ramblings, and pulling this up for perusal by the late crowd.
