I have a 2.9 Hattori and a 2.10 666. Both are excellent bats. I wen't a bit lighter with the Hattori as I usually use a 2.10 to allow for the difference in pick-up with it having a lower middle and considering the amount of wood in the blade it picks-up well. The 666 picks up very well, a lot lighter than the dead weight - prob 2-3 ounces lighter.
As Canners and 97 n.o. have said, you can't go wrong with H4L - I am very pleased with mine. The easiest way is to PM or email Matt with your specs and go from there.
