I was kind of in the same boat as you wanting to try some lighter arrows just to pick up some speed in case I decided to join the 3D league this year. I wound up picking up a half doz. Victory V-Force HV's on ebay for a great price. I've just been goofing around with em with different fletchings, tips, etc. The 400's weigh 6.1 GPI. So far so good. Don't know if will hunt with em or not.
