In the bang for the buck category, the gold tip arrows are up on top of the list. The quality is there but the price will not break your budget. As far as spine goes, for the gold tips, shooting 60lbs, I would look at the 5575.

There are plenty of other good shafts out there, the Beman ICS Hunters (what I shoot) are very popular and have proven themselves as very reliable. A bit more cost than the Gold Tips they are still very good arrows. For your setup the 400 spine is what Beman recomends. With your draw weight and arrow length this puts you right in the center of the range for the 400 spine arrow.

Easton also has a carbon shaft (same as the ICS Hunter) just marketed under the Easton name.

I am sure that others will chime in with other brands and shafts, but these are the ones I have used and had good luck with (performance vs. price)
