basspro arrows?

Anyone shoot the blackout envy arrows from basspro? I just got my compound bow last year. I have been practicing with the X5 arrows but found the X3 arrows specs are a little better so I ordered a few of those yesterday. Anyone have any experience with those?

I used them last year, bought a dozen and had sawed down at BPS, shot three to test and shot fine. Got home, and 4 of them flew crazy. Bought a dozen of the goldtip xt hunter and all of them fly true. They had them $109.95, but you can mail in a paper and get a $20 rebate.
