The Devil Hawk is a low profile putt and approach disc with a bullet shaped nose and a bead on the wing for stability. It also has a thumb track design for added control and feel. This disc is basically a Wizard with 1/4" of rim depth taken out of the middle. This is Gateway's most over-stable putt/approach disc.
The Sure-Grip™ or "S"-Series, is a matted material and is a high end version of the "DX" or "D" plastic of from other companies. This type of polymer offers a firm, solid feel with a grippy surface and great performance in the rain or extreme heat. The "S" plastic allows the disc to break in slowly without changing its flight characteristics after just a few hits.
