No, I fletch my own now, and I never bought arrows with blazers either...I like to know exactly how much helical and offset is on em, most times thet don't know unless it says it on the box...but Im sure they would be fine...go for the feathers dude!!
I shoot those same arrows except I have either Blazers or Vanes on them. Great arrow for the $$$$. I have bought about 5 dozen in the last 4-5yrs, given away probably a dozen to help guys out, RH'd a total of 15 of them, busted a bunch of nocks, etc. GREAT ARROW for the price, but you can get them raw and have 'em done up however you like also, that's what I do. Call the Wheeling store and have them cut and square a dozen at my length and mail them to me. That way all they need done is fletched and inserted, and are ready to use. See my avatar or the recent thread I started "Now I'm confused ( http://forums.bowhunting.com/showthread.php?t=5795 )" those are all Cabelas' Carbon Stalker Extreme Arrows.
