I tried knocking knuckles and did not like it(as a player). DDs tried it and didn't like it. One isn't better than the other imo. All comfort. The problem coaches have is simply this...They don't know how to teach a kid how to grip a bat. Most that are trying/using a box grip place the handle on their palms and squeeze the crap out of it.Simply, which is the correct grip? And what are pros cons each grip has?
