In 2006 APS made us one with a Forte RTS 2.5" ID tube, Forespar UXP 200 composite ends, spectra trip line, and center whipped/epoxied D-rings. It was scary watching it bend while reaching in breeze with the foreguy tight. Looked like it might snap at any moment. Since we don't use twings and depend on the foreguy to keep the pole down, it really should have had a proper bridle. Co-owner Mike who did bow in those days disliked the ends. Since he bought, he chose to sell it. Cost a bundle to have it shipped. If I were to make another, I would make one the same size as the standard aluminum pole, use ends to match and would probably have bridle for when the breeze was up.
