The Union had one goal in mind. It Unites the two best materials in the game. Scandium-Titanium mixture gives you lightweight and strength you need to play at the highest level. Adjustable Butt end adjust along the handle to your preference. Just tighten down and tape for a locked-in sure fit design. Dynamic Wall Taper tapers the wall thickness of the shaft. This allows for added material in areas the shaft needs it while cutting weight in areas that can afford it.
