And don't think for a second that added weight to your arrow is (always)a BAD thing.
Most just prefer not to add weight on the back end if they know much about the workings of an arrow. Weight on front is good, but adding weightto the back canbe most generally is Not Good.
If anyone uses lighted nocks, wraps, vanes, etc. Be sure to check your FOC. If it's not high enough keep your shots close.
