If you use 28" arrows, at 8-9 grains per inch vs 10.4 gpi, the weight difference would be something like 40-68 grains. Figuring 1 fps for each 3 grains of arrow weight, you're looking at maybe picking up some 13-22 fps. Hardly earth shattering, IMO.

It's not going to increase your effective range by any more than possibly one yard on either side of the deer. It's not going to skewer a string jumping deer any better than your current arrows would. If the lighter arrows make your bow more noisy, it could even make the potential problem worse. And that's all it is, a potential problem.

It's your call. Is the small gain in speed worth the expense of high grade carbons? If not, is the small gain in speed worth dealing with the problems that come with lower grade carbons?

And, besides those two points, is this one: Can you shoot good enough to even see a difference between good arrows and junk? That's a big point that not many people think about when they hear folks raving about how great carbons are. You'll find that most people who complain about the quality of carbon arrows are also very good shooters. The ones who rave about cheap carbons are usually just good enough shots to be able to hit the broad side of a barn... from inside the barn... with the doors closed.[8D]
