From the manufacturer

The game has changed and so should we. Stepping back, we realized amateurs and professionals around the world have been clamoring for a heavy-rolling, fast-migrating core akin to one of the most famous of all-time: The Shape-Lock HD Core. This shape can power through just about anything. “HD” is short for high density, which lowers the RG and raises the differential of the weight block. And with SPEC at the helm, expect heavy roll with no shortage of higher scores and more strikes.
