Pros: After dry swinging a couple dozen BBCOR bats - and demo-ing the '15 515 Omaha at our local shop - my son agreed to give the Assault a shot. Balance is fantastic. To my player, it was the best feeling 1 piece Aluminum bat on the market. The handle bias in the weighting makes the swing weight feel lighter - and the benefits my son recognizes are: 1 - more swing speed and 2 - better control when he needs to adjust mid-swing. Really seems to drives the ball well. This bat is a really solid value at current (October 2014) price-point. Already a favorite bat of some of several of my son's team-mates.
Cons: There are only 2 that come to mind. 1. Why did LS ever drop the Omaha name? 2. The metallic paint is sharp - but scuffs and chips easily. That said - I like the quiet color-way and quiet graphics. The bat is a sleeper.
