I'd opt for the carbons. Do some homework first, though. There are carbon arrows that are entry level and cost about the same or even less than aluminum. The there are mid-level and upscale that can really whack the pocket book. It's your choice. The thing with carbon compared to aluminum is that you will rarely ever bend one. They are just more durable than aluminum in that respect. They also fit a much broader weight range than aluminum in that if you turn the bow up 5# they should still work where as with aluminum you will probably have to get a stiffer spine.

Aluminum usually has tighter tolerances than cheap carbons, but if you get cheap ones they won't stay that way. They can bend more easily and dent if shooting groups. Usually heavier (but not always) than carbon.

I've been shooting carbons since their infancy. Shot aluminum long before that. My arrow of choice is some sort of carbon whether it be an ACC type or all carbon.

I cn't remember the last time I lost one, but a pick a dozen and they last me as long as ten years. I change during that time because they just keep improving the tolerances as time goes by. It's a very competitive industry.

Suggest you get on several websites and check out the different brands and models Gold Tip has their Expeditions for entry level. Easton has several models, as does Carbon Express. These seem to be the most popular.

List your bow weight, draw length, length of arrow you intend to shoot and I'll recommend a particular arrow. You need to get the spine right whatever you choose.

As for the rest, the Whisker Bisquit has several different size inserts for different diameter arrows. Should you want to use a large diameter aluminum all you have to do is get the appropraite insert.
