Storm. We're talking Storm.
My first "most favoritest" ball ever was the Firestorm. Although I just found another one, and it definitely has a place in today's game, I've shot some really, really, really big scores with my Deuce.
And - after I thought it was dead, it resurrected itself with a little help from scotch brite.
So, I think I'll say Firestorm and Deuce.
