I really hate Zing-It. It gets tangled way too easily. Brand new or broken in, it doesn't matter. You can play it all out on the ground on flat concrete, no twigs, and still when you throw it, you'll watch a big mass flying away from you. At least, that's my experience. I had much less trouble with Rhino line, though the last 300 foot roll I got had manufacturing defects and kept breaking. It's so frustrating. I'm going to try some of that gold-plated Dynaglide, just to check it out. I like the thinner lines in general, you can throw them much farther.
