This is a lightweight, composite shaft with a foam core. The foam core adds strength, making the shaft feel solid, adding power to shots.Pros:
A lightweight, but solid composite that doesn't get too cold/hot depending on the temperature. Shaft is a full 1" diameter and adds power to your shots.Cons:
It would be great if this shaft had the grip pattern like other UA shafts. Also, be careful when attaching the head - because of the materials used to make the shaft, the screws can enlarge the holes in the shaft creating rattle. I would recommend attaching the head with two screws.
