All for trying new things in BP to see what you like or what may work surprisingly well for you, but I like to stick to one bat for games and the majority of BP work.
IMO, timing and quality of contact are the two most important aspects of hitting, for hitting bombs or gaps. For me to nail those two aspects I need to be relatively consistent in swing weight. Switching bats during the game is kinda like gambling, you may go big but most of the time it doesn't end well. Batter controls how and where the ball is hit, not the bat.
Found I need about 100 hits with a new to me bat before I feel consistent enough to judge it, you may be different.
