I personally prefer a bow, helps me go over the top, and adds decent pick up to a 3lb plus bat.
But, with the increased want for bigger edges, and the flatter profiles bought about because, it seems very pronounced bows are disappearing from the shelfs.
In fact I believe it's just be asain made bats that still offer a pronounced bow.
Mainly the Asian mades, except for Salix, of course. In my opinion, they make the best use of the bow, and I believe it is a major reason why their bats pick up so well. I also know that, having visited their place a few times, they take pride in creating their bows, almost as if they are a work of art, which apparently not every bat maker is capable of achieving.
