A quick read-through of stores shows the carbon express blue streak shafts and arrows selling for one hundred and fifty to one hundred and sixty dollars for the basic shafts and about one hundred and seventy to one hundred and eighty dollars for fletched arrows. The Select varieties are going for about five to ten dollars more for shafts or finished arrows. For the dozen carbon express arrows tested the weight tolerance came out to about zero point four five grains with the stated tolerance about one grains so these shafts are well within the weight tolerance. The stated specification for straightness on the shafts is about.0025 for a total span of.005. While overall the shafts are extremely straight, there were two shafts, numbers two and six, which fell slightly out of tolerance on straightness. Carbon Express's spec for spine for the Blue Streaks is about 0.0025.
There was a total difference of 0.004 and a range of about 0.002 across all of the dozen shafts; which is very impressive indeed. Dual Spine Weight Forward technology is a breakthrough in arrow design that delivers unparalleled accuracy and performance. The fusion of two different carbon materials creates two spines in one arrow, resulting in rapid recovery and guidance control. There has been a lot of questions and some controversy over exactly what this means. In order to have a complete review, let's take an in-depth look and some measurements of these shafts. The shafts have very definite and distinct patterns of weave on the front and back of the arrow. The back of the shafts have a much larger weave pattern that is about nine and one eighth inches9 1/8 long from the back. Under the arrow label the transitions occurs to the smaller, tighter pattern. In theory the front section should weight more per inch than the back.
The tester took a 6.025 section from the back (which is all I could get before getting to the label and the tester didn't want the label to affect the outcome) and from the front and weighed them. These sections were first cut then precisely ground with a F.A.S.T. tool to the exact same length. Exactly the same weight which comes out to eight point two grains per inch. Each of these sections have only one of the weave types. The tester decided that to be thorough I should weigh a larger section so I took larger section from the front and back and weighed them again. This time the sections were thirteen and five eighths inches and the back section included the label area. Using a solvent the tester was able to remove all traces of the label. Once again, the sections weigh precisely the same amount. It appears that there is no difference in the weight per inch of the front versus back and the shafts themselves do not contribute to any weight forward.
