You'll get lots of answers, and all of them are likely to be fine choices.  Lots of different ways to decide.

Personally, I use carbons (Gold Tips) on my fiberglass bows and woods (Sitka Spruce and POC, occasional hardwoods or rivercane) on my selfbows.  I do this simply to match asthetics, and I find it easier to tune the wood arrows to the selfbows.  But mainly, it just seems to "fit" better.

I use aluminum arrows which you can see in my signature. With my 42# recurve, I shoot a 160 grain STOS 2 blade glue on broadhead and with my 37# recurve, I shoot a 145 grain STOS 2 blade glue on broadhead.
