Honestly, after using the original ball shifter for two years now, we would like to see a bit more spread than 2.27.
2.57 is probably closer to where we want to be, although even that may not be absolutely ideal either.
Ahhhh compromise, the bane of all things Engineering!

If you are willing to use 9-11 tooth sprockets from McMaster and Vex 28-33t plate sprockets you can get 2.92 with standard Vex Gears.
Fast: 30t CIM, 44t Ball Shift
Slow: 14t CIM, 60t Ball Shift
Final: 10t Sprocket, 30t Sprocket
