Marucci sent this bat as a warranty replacement for the green hex alloy. This bat is way hotter out of the wrapper than the original hex alloy and seems to be getting better. The stronger alloy makes this bat way more durable than the original also. The hex alloy one had more dimples than a golf ball after just a couple weeks of use. The 2 doesn't have a dent or ding yet. My son has the Hex Connect, Hex Alloy 1, and 2 in his bag and the Alloy 2 is by far his favorite! I'm going to buy another one to stick in his bag just in case something happens to this one!
