Weight & Spine tolerances are very good on average (you get a few clunkers like everyone else who makes carbon arrows). Straightness is a crapshoot, and I'm starting to see the degredation of the straightness in my original doz (they are developing nock or point end wobble)[:'(]

When they are straight they shoot phenomenally well! Scary accurate!

Love the HIT!

A+ for the idea.

C- for overall execution.

They need some refinement. If Easton can do it, they will be the hunting arrow of the future AFAIC. But right now it's a big "if".
