.52Cal was good, weighted different for me, i don't like the end load that all the new bats are being made with, it was kind of a log for the first 100 swings, not too hot out of the wrapper, mine wasn't at least, and i almost sold it then, had a couple more rounds of bp on it and i changed my mind, when it opened up it was pretty sick, fairly soft feel i though, broke between 250-300 swings though
