Re: polyurethane tubing
This stuff is excellent as semi-slip material. It isn't grippy like rubber surgical tubing, but the problem is that it may not pick up as quickly (in my experience-we put tread on our bottom rollers to aid pick up). You can pretty much jam balls down our hopper and then pull them out just as easily.
Going back to the welding discussion, 766 used the yellow hollow cord this year, and we just welded it together with a heat gun. We held the ends in the heat until they melted slightly and put them together when melted, waited for cooling and dremeled (with that sanding attachment) the surrounding blobs off. In two regionals we've never had any loop break.
Technology is cool!
