RE: Need advice with a conversion setup...
2 carbon arrows that I have had good experiences with would be Carbon Express Terminator Select, and Carbon Tech Cheetah. With the Terminators, I would get the lite version, if you want to pick up speed, but they are pretty consistent, and tough arrows. They are also fairly quiet when drawn through the Whisker Biscuit.
Carbon Express Cheetahs shoot very well for me, and are very light. The Whitetails are also nice, not quite as light, but less expensive.
