While this disc might seem to overlap with the JLS at first, I found a use for it. It accomplishes the same shots, but with its lack of dome, different hand feel, as well as a bit less glide than the JLS, I find this disc perfect for forehand. It might be my imagination, but it also seems more torque resistant than the JLS for forehand, although this might come down to solely getting a cleaner release, going back to it being a more comfortable sidearm grip, and lack of dome. If this disc feels good in your backhand grip, you probably don't need both the Polaris LS and JLS. Lastly, while I agree with the glide, turn, and fade numbers, I think the speed on this disc is probably closer to an 8. Underrated disc!
