Originally posted by Terry Green: Mini or regular aquarium tubbingh works better than weed line.Cut it about a 1/4 inch longer than the shaft....and when you glue in the insert it will 'scrunch' it a bit for no rattle.I also put some glue on the bottom of the insert to the tubing is bonded to the bottom of the insert.Great way to up your arrow weight bout 100 gains.
Originally posted by Brent Hill: Tried it, too loud unless you glue it in but there are better ways to gain weight. Brass inserts and weights are better ways to gain weight and you get a quieter, more consistent weight system that won't move within the arrow ( tip to knock like the line will try to do.)
