For an arrow to hit that much lower than your others, nodog, it'd have to be a lot heavier. To be that heavy, that'carbon' arrow ofyours has to be fiberglass/carbon composite.Carbon Express Terminators are like that, for instance.

And yeah, they are a LOT heavier than all-carbon arrows are. My 6075 Terminators weigh out the same as XX75 2315's. But they'reso muchbetter... more consistent and more accurate... than plain carbons in the same price range. They'renot as fast or flat shooting, but I can judge yardage. I want arrows that hit where I aim them instead of just close to where I aim them.
