They definitely could be used for the reasons above; it makes absolute sense. Most carbon arrow size wraps weigh about 10 grains at full length. But also: Were they a sponsor's wraps (Bohning perhaps?) and did he use them under the fletch too? (Two wraps on one arrow?) Thinkabout thiswhen you look at the cost of wraps and how much it actually costs to make them... (Hmmm. Hey, how can we get people to buy and use more wraps?)
