They are heavier, but to me they are worth it. I weighed a 3/8 inch balsa dowel and the DB fiberglass pushrod material (about .3 inches). The fiberglass rod is about 35% heavier. That 35% increase in weight more than makes up for itself in strength and durability. I have researched arrow shafts and the local archery shops only sell them in large quantities and I don't feel like spending that much money at once for pushrods. Maybe there are other shops that sell them seperately. I just don't have the time. The LHS stocks them and I live 3 miles away. They are around $6 for a pair of 36 inch pushrods and the end fittings.
