I love how people see a thread, click on it, read down a handful or replies and take the time to tell a very new member that their question is stupid and they should have search for their question before cluttering up the board with foolish non-sense about bats that come out every couple months and or change performance with use. Fortunately for me I can afford One decent used bat and a couple cheap new ones for everyone to beat on so I don't need opinions of people with greater access and availability to bats I cant afford or haven't had the luxury of using for anything more than a couple swings at a tourney when its 95 degrees.

But don't worry, it gets better and if you weed out the "experts", "rec league heroes", and "internet superstars" you will find lots of good people with similar interests and invaluable experience and knowledge.
As for an answer to your question, here in Maine when we get our winter ball groove on, metal bats and older bats we aren't worried about cracking are the rule. After 40 -45 degrees its not as important but mikens and seem to be the most durable, then worth. Combat and demarini are the most susceptible to cold, Easton is hit or miss. Hope it helps and have fun, that's why we play, right?
