The Current Avalanche Pearl (Lime green & Black) is much stronger than a Pearl Beast. I'd guess the Avalanche Slide would be weaker.
My money would go to balls like the Cherry Vibe, or maybe the Street Rod Pearl.
A Pearl Beast today would still not be a dry lanes ball but it would not handle true medium oil either, like the Freeze or the new Avalanche Pearl can. It would be a light to medium-light oil ball
