Rich Porter of Isopop has taken his background in architectural design and started applying his scienceto hoop making, tracking down a variety of different tubing options and putting nine different options to the test. He writes, "Polyethylene is the standard hoop tube. Of all the tubes I’ve tried, in my opinion, it’s the best tube for most hoopers. For those who hoop extremely fast, I think High Pressure Polyethylene (HPPE) is a better tube. It’s slightly lighter and slighty stiffer. Polyproplyne is also a great tube. It’s even lighter than HPPE but springier and less stiff than HPPE. It almost feels like kids hoop tube." He's created a table of the 9 tubing options he's tried as well. Isopop
