RE: Whats The best carbon arrow?
You will get a lot of answers for this one, and part of it depends on what you want to do. I would say for arrow to arrow consistancy of spine, weight, straightness, ACC's are your best bet. Many other manu's make a great arrow, but as a rule, you will pay for the best tolerances and quality. Gold Tip makes some nice stuff, particularly their Pro line. I have liked what I have seen from Carbon Tech, although I have not owned any.
It really does depend on your chosen need. Hunting vs shooting 90M outdoors are two very different needs. You really need to match equipment to the purpose.
