OK, OK, I know it sounds strange but hear me out
Last week at the local archery shop, I was looking at some of those PSE radial weave arrows. The guy behind the counter says, Hey, try this Kev. He hands me three pieces of arrow shaft from three different arrow brands. (they were the cut-offs from trimming new shafts, about four to five inches long) He then hands me a pair of pliers and says, "crush em', see what you think."
I crushed all three. The first 2 were a GT hunter and a Carbon Force Extreme. I crushed them with out much of a squeeze at all. In fact it was surprizingly easy. I then squeezed the Radial Weave shaft. I couldn't believe it, I had to squeeze the pliers with all I had to crush that shaft!
I realize that we don't put this type of force on a shaft, but it really has me thinking. Just interesting, that's all.
