I haven't bought any arrows in a while. If you can still get the Carbon Express Heritage,they will be heavy enough without extra weight inserts and they are very tough. That's why I haven't bought any in a while. I've shot field points into trees and wiggled them out without any damage.

FYI
I like them fairly light. Rod Jenkins shoots way lighter than 9gpp, more like 6gpp in ILF bows of low poundage and gets complete pass through.

You need a small diameter shaft, cut on contact sharp head, and a well tuned arrow.
