Pros: Weight is distributed evenly, large sweet spot, great pop out of box, the grips are great, low hand vibrations. My 11u son loves it. We bought this for our son after his 2014 -10 Portent cracked. He plays 11u travel ball. He loved that bat so we decided to go with the 2015 Portent. His bat speed was very fast with the drop 10 so we decided to try the -8. He is a power hitter and hits the balls even farther and harder with this. We played a tournament this weekend. Almost everything he hit either hit the fence or bounced to the fence (fences were 300 ft). The balls came screaming off the bat! Amazing. His team mates now want his bat! His dad and I were impressed with the 2014 Portent, even more impressed with the 2015!!! Love Combat!!! Btw, the 2014 that cracked, Combat was amazing in customer service and promtly sent us a new replacement.
Cons: non yet
