Pros: The Mako feels more end loaded like the XL1. It virtually feels just like the XL1 but 1 ounce lighter. When my son hit both the Mako and XL1 on the sweet spot, the XL1 flew farther. My recommendation is that if you are strong enough to swing the XL1, get the XL1. If you need your bat a little lighter get the Mako or XL2 or XL3 to save some dough. If you need more swing speed, stick to the S Series.
Cons: None. Great bat for the person that can't quite swing the XL1 but the S series is too light for.
