I am signing up for the platinum membership and get to select 4 balls. I have no idea what 4 to choose. I currently have the Ogre(2000 abralon) and the Bronze Centaur.

I am intrigued by a few but not sure which ones to get. I like the Immortal Solid, Frankie May Gryphon and G-3 Gryphon, but I don't know if I should go with those 3 and something else or do a different combination.

What do you guys think I should get?

The best ball is the one that knocks down all of the pins!
