I regularly use Hagoromo chalk on a personal chalkboard and I always break new sticks in half before use. For me, it feels more comfortable to use smaller pieces than large ones. It allows me to hold the chalk with more fingers, and avoids the awkward position where you have to hold the chalk like a pencil with a few inches of chalk resting on your hand. However, some friends swear by full, long sticks, so it's very much a matter of what you're used to.
