I think it is time to retire my Storm Dimension - basic stack drilling pin over ring finger.  I am considering staying close to my comfort zone - RotoGrip/Storm but have been reading about the new 900 Bank.  

Any suggestions on replacement ball for my Dimension ? - Bank, Cell Mutant, Prodigy ?

Would anyone consider putting a RICO drilling on the BANK.  I have this drilling on my old Blue Vibe might consider doubling up one with, one without.  thanks to all.
