I recently bought a new dozen arrows, Carbon Express CX 300. They are the same arrows I have used since I started shooting. The previous dozen or so I bought came in a box already fletched with a small amount of helical. Now these ones I bought the other day had to be fletched and the guy put them on straight. I gave him an arrow for reference, but I guess if you don't ask for anything different then they put them on straight. That seemed to be their policy anyway when I asked if I could get them re-done. I know I will have to have them redone at some point. For the time being I sighted my bow to accomodate the new config. My questions is this: Does anyone know what degree of helical those CE CX 300 arrows come with from the factory?
