RE: Easton Lightspeeds
Price seems OK for them. I shot them several years ago and foubnd them to fall well within specs. Because they are a light shaft they will be fast. Maybe a little fragile, but don't miss. Don't shoot rocks and trees and don't shoot groups. Arrows aren't made for that.
You may give up some potential penetration, but if you're shooting them properly spined for anything above 50# or so on deer sized game you should do well with them.
