Yep that is fair...

straightness tolerances for easton shafts use TIR...total indicator rating over the entire length of the shaft.

Spine tolerances are in the easton tech bulletin..I don't remeber the eaxact numbers...they are minute...

Spine is measured around the circumfrence of the shaft... the arrow is held at two points 28" inches apart..then the weight (500 grams?) is suspended in the middle.

Shaft weight does not include the unibushing
