I recommend bwp - Brookville Wood Products
Model 243 - Hard Maple
Used by Minnesota Twins Justin Morneau &
New York Yankee Johnny Damon
They advertise over 150 professional players use them.
I live near enough to the factory that I walked in one day, picked the wood, had it painted and laser engraved right there while I watched the whole process of how they made the bat. This is a small factory that is really producing quality bats.
