After responding to a different thread regarding the Depth Charge I was thinking what are my favorite Storm Pearl Particle balls? In my opinion pearl particle bowling balls have a very unique roll and for about a 10 year period Storm was making the best on the market.
So the question is what is your favorite Storm (or RG I guess) Pearl Particle ball of all time?
My honorable mentions are the X-Factor Ace and the Shift. The Ace is probably my second favorite of all time. Very controllable hard arc that I could a find a line to the pocket in almost any shot other than bone dry or soup. The shift was a reasonable X-Factor Ace replacement with a hair more length and a bit more backend reaction in dry.
My favorite Storm Pearl Particle by far though was the Core Power LE ball I picked up at the 2003 US Open. This ball was the definition of smooth. Early roll but it still retained energy to drive through the pins. This was my favorite down-n-in ball of all time.
