You can't go wrong w/any of them -- as long as you match the ball to what you normally play on. (Terminator on very dry, Buzz or Hornet on heavy oil, etc.)
In my oh so humble (but always correct) opinion -- I think that the Black Pearl can be the most versatile of the current LM line. All of them can take to surface adjustments really well -- but I've seen the BP in fresh soup as well as 3rd shift beatdown lanes, and if you just touch it up a little, it'll rock every time.
I can't say right now about a Yeah Baby, because I just bought one from Just Joe, and haven't drilled it up yet. But if it makes as big of an impression as the voting suggests -- and if you can find one (another challenge), then I'm sure you'll be involking the name every time you roll it.
