When defending with an angled bat a bow helps keep the ball further behind the hands... i like that . I also like the assistance in hitting over the top you get from a bow ( call it placebo , but i swap to a straight bat , play the same shot , it feels worse ) . Lastly, pickup with a bow is better . This is subjective but not placebo . Is bow , is good !
Btw , never had any pressing problems on the toe from bowed bats or anything else bat makers say re the adverse effects of prominent bows that are cut into the blade .
