If you are changing to carbon just be aware that you get the spine correct, meaning stiff enough. If you err keep it on the stiff side. It's not a hard choice really. Carbons are usually adaptable over a larger weight range than aluminums. Whereas you might need to change arrows for a 5# change in bow weight with aluminum the carbons often cover 15-20 range. Whatever you choose be sure to check the manufacturer's spine charts.

There are different grades and straightness factors, too. You just have to decide how much money you want to spend. For instance, with Gold Tip there are arrows that are straight to about .006". The there are some that are .003". Then there's top of the line that go .001". They are all basically the same shaft sorted by tolerance and priced accordingly from about $60 to $100 per dozen. Go middle of the road for a good compromise.

Other manufacturers are much the same.

As for broadheads, I don't jump on the bandwagon every year like a lot of folks. I have what works well for me and stay with them for years. I've been using InnerLoc for several years now. A similar built head is the Muzzy. This year I took a look at some new ones and one I like is the Slick Tricks. I pay particular attention to how the blades are locked into the ferrule. The stronger the better.

A relatively new craze, and a good one, is the short stubby heads with stainless steel ferrules vs aluminum. With less blade surface there's bound to be less wind planing and a stronger ferrule. Just another issue to look at.

It's a long time till next season so you should have plenty of time to do homework. And most assuredly someone will come out with something "the latest and greatest" and everyone will be touting it.

Good luck.
