Pros: We got this bat in -11 for our son for his birthday; was hesitant about spending $100 but it was worth it. He was moving from a -13 reflex and the -11 version was the closest. We also went from 27 inch to 28 inch so we increased the weight by 3 oz. It has a good sweet spot and balance. He has hit about 50 pitches this past week and besides having to adjust to the added weight he is still driving the ball up the middle and just as far as his old reflex bat. The 2 5/8 barrel is also an adjustment but he seems to like it better than the 2 1/4. The 5150 is a good bat and you will not be disappointed.
Cons: None so far; just having to buy it and him having to move to a -11 instead of -13.
