Although the Terminator is, by the book, stronger than the Black Pearl (it is earlier, being a solid, and handles more oil), one factor that must be considered when you see what appears to be an apparently contrary situaton, is that house blends have the potential to hide or mask differences between balls.
There are several reasonable explanations for what you may be seeing, even ignoring the "house shot" factor.
But the fact remains that there are several balls from Lanemasters/Legends that can fit in between your two strong ones and the Buzz.
The World Class Reactive is a highly polished solid that can be very flippy ( aminor surface tweak or a control drill can help that).
The Masterpiece is a strong pearl that will also fit in between.
The Big-R-Bang is also a highly polished solid but its core makes it very flippy, possibly the flippiest ball Lanemasters makes.
Due to your higher ball speed, I'd be inclined to think the WCR would be your safest bet, IF you want to stay with LM/L.
