Got it since I needed a really durable Bat because of the lower Temperatures we get in Germany during our Fall and Spring Tournaments.
Breaking in with 52s goes only half way there, 44s get the second gear going and after total of 500 Cuts you got yourself an amazing Hot Bat that gets more hotness after every usage without breaking.
Haven't heard from Softball community or internet that somebody managed to break or destroy it at all.
Since 44 core USA balls are almost non-existent in my Region, I am using USSSA balls 44/375 and Backlash2 is hitting them pretty well.
