The four-strand 35-foot Rattler GT4® Lite Heel Rope is easy to handle, with lots of body and a CoreTech core. Many professional ropers use this team rope in the practice pen or to compete with. It holds up great in the winter because it's made of 100% nylon fibers. Many northerners reach for this rope because it doesn't get that back swing in the cold weather. The GT4 has a CoreTech core and lots of body. Lots of body means a larger loop that stays open better than any rope in the arena, for more consistency. The GT4 is also much more durable than any conventional three-strand. So, if you want a long-lasting life and body, you'll pick up the GT4.
