Right now I'm shooting Axis Nano's and there a pretty decent arrow not to badly priced. About 120 bucks for a dozen I think. Shot Beman ICS Hunters good arrow as well along with Easton 2413's. The Flatlines by Easton are pretty sweet arrows as well.
Although I don't understand why your worried about wieght. What you loose in wieght you make up for in speed with Kentic Energy. What you loose in speed you gain in wieght for Kentic Energy its really no problem either way and light or heavy either way you go will work more than fine. All about the shot placement.
