bigbulls,

Id not only like to see some standardization on spine deflection, but on variance, too. Ther only tech charts I've seen, and I haven't seen them all, were on ACC's and the tech bulletin stated that the variance in spine of them was .005".

Wouldn't it be nice to know how well those $120/doz, .001" straight, Pro quality arrows are really made?

MIKE,

You didn't make a mistake. Arrows are measured from the deepest part of the nock groove to the end of the shaft, si 28 1/2" is correct. Besides, 1/8" won't make a difference.
