I spun all twelve of them and I don't think there was a straight one in the bunch.
That is about the same as I have found. I have also found similar results with the AC super slims.
Personally I think Easton should stick with aluminum shafts.
I too am thinking about tinkering around with the CX Edge shafts this year. I find that Carbon Express shafts are much better on their tolerances than many other manufacturers. Hopefully this will hold true for the edge shaft.
