I just asked the guy for some inexpensive arrows, didn't know they were aluminum until just now, when I looked at the box. Yes, I agree, wood would make more sense for these bows.
Do you make your own arrows?

Well, I prefer wood for the wood bows, but nothing wrong with aluminum. There are some pretty good articles on fine tuning archery tackle. But not to confuse the matter now.
Spine is measured at 27" for AL (I think) and 28" for wood (that I know). Increasing the arrow length has the effect of lessening the spine or stiffness. Similarly cutting the arrow shorter than the spine length makes it stiffer or increases the spine.
Yup, make my own arrows. Not real great ones, but they fly good enough for me.
