Yesterday I hit a round of 50 balls using 52 300's and was impressed with the performance considering the bat is no where near broken in. Out of 50 balls on a 300 field, 5 went out, about 25 one hop the fence, the rest line drives and grounders. I did like the sound of the bat " has a nice crack sound" on a few hits. The temp was late 60's 10-20 mph wind blowing in from center field. Not sure performance would be as good with hot temperatures of 80+.
