Ok all you arrow guru's

Im wanting to try out the new Easton XX78 super slam digital. Easton's site lists the sizes as 510, 460,420,400 and so on. I know what size i want, its the 420 it has a .423 deflection. Now the problem the only sites i can find them on list the sizes the old way, 2114, 2117, 2213, 2216 and so on, so which one is which? Is there a conversion chart anywhere?

I can always wait untill tuesday and call but just thought someone might know

2213 = 0.460 deflection
2114 = 0.510 deflection
2117 = 0.400 deflection
2216 = 0.375 deflection

these numbers are from the easton shaft selection program

So I would say the 2117 best matches.  Just for reference the 2215 has a deflection of 0.420 and the 2312 has a deflection of 0.423.
