Pros:  My 11 yr old loves everything about this bat. He previously had the Nighthawk, but i could not find a used one. I do believe this bat has more pop than the Nighthawk.

Cons:  None thus far

Comparing the 2017 Generation -8 and the 2017 Covert -9, where are the balance points? Does the Gen. have a lighter swing weight due to a balance point that is close to the handle, or are they fairly close in swing weight?

The Generation and the Covert should be very similar when it comes to swing weight.
