QUESTION: Should I order this bat stock/untouched or Heat Rolled with Progressive Pressure?
ANSWER: If you order your new bat Heat Rolled with Progressive Pressure, it will be delivered to you completely and evenly broken in. This process adds 20-40ft of distance to your solid hits, increases consistency, improves durability and adds 2-3 business days of lead time to your order. If you plan to use the bat in an official game or event, please verify the legality of our process with your league or sanctioning body before use. We (LongballBats.com) do not encourage the use of a Heat Rolled bat in any game or event where it is against the rules. Click here for details about our process!
