Sorry if this has been posted before (as I don't frequent the Big B forum much), but I was wondering the differences (if any) of these 2 bowling balls...besides the name and color! I was looking at getting an Ultimate, cause my buddy LOVES his OI and UI, and I LOVE my Uranium Pearl (get same reaction as his OI), so I was gonna get either an UI or a Solid Uranium. BUT, I was looking at the booths at Nationals, and saw the Red Alert 900, and think it's the same ball as the UI...please help me out here. Thanks in advance for your time people...

PS...Am trying to give Big B more representation in my bag, since my only ball I currently use by them is my Bionic Zone 1 (and Uranium Pearl and Carbide Bomb if we wanna get specific)!
