PERFORMANCE TECHNOLOGY: New Wall-Thickness Profile: Repositioned and extended the wall thickness profile. You get the highest maximum BBCOR performance profile, and extended longest sweet spot, along with the fastest and lightest swing weight New Power Hitters Sweet Spot: Extends and optimizes higher performance in the power hitting locations on the barrel towards the end of the bat New Lighter / Faster MOI: In general, the lower the MOI, the faster / lighter the swing weight of the bat. We have lowered the swing weight of the Strato 2 by 200 points, and it is now our lightest alloy BBCOR bat New Lowest Compression: Lowered compression in the barrel by up to 16% in precise locations, and an average of 11% across the length of the sweet spot New Armor Alloy Ultra: Armor Alloy Ultra undergoes a special heat treatment to increase its strength and allow it to flex without denting or cracking New CNC Precision Barrel Technology: Grooves allow the barrel wall to be as strong as a thick wall but perform and weigh as light as a thin wall Composite Hyperwhip2 Endcap: Sleek design and carbon materials save weight at the tip of the bat for a faster, more efficient swing and larger barrel Patented Axe Handle: Patented Pro Standard Axe Handle provides an even better connection and fit, so you can swing faster with more control every time up ADDITIONAL DETAILS: NOTICE : Baseball/Softball Bats are only eligible for return if they have not been used.
