RE: carbon arrows?
" Best" is a very subjective term. Some are " better" than others but it is difficult to say that one is definitively the " best" . Having said that though I would probably suggest that ACCs are the most well thought of carbons on the market though they are not true all-carbon arrows but rather an aluminum/carbon composite.
In this category of equipment price definitely dictates quality...though there are some exceptions. If you are just looking to try them out for the first time then there is nothing wrong with some of the inexpensive carbons but don' t expect to have the straightness tolerances or spine consistancy of the more expensive models.
Hope this helps.
