LONE STAR DISCS HARPOON
The Harpoon is an extremely consistent, versatile, and reliable midrange. Whatever task is at hand, the Harpoon can handle it. Apply power and it will hold whatever line you put it on. Throw with “touch,” and it will fade slightly. Perfect for approach shots –on or off the tee! Forehand, backhand, or overhand–the Harpoon is ready!

From Lone Star:
Delta plastic is a very unique blend, coming in two variants: Delta 1 and Delta 2, both of which are stiffer than our Victor plastic. Due to the rigidity of this Delta plastic, these discs are inclined to break in at a faster rate, which is comparable to other companies' base plastic blends. Delta 2 is stiffer than Delta 1, and while both plastics are incredibly stiff, neither plastic has the specific gravity required to float like our Victor plastic blends.
From Maverick DG:
Delta 1 Has a semi-rigid rim, but semi-flexible plate.
