A2 and Flex Numbers

[scottac29]

Hey guys, just got a new 66.5 A2 and its the first brand new ski I've had in a while. There's a sticker with flex numbers on it which read 68/104/130/144. For those in the know, are there certain numbers to look for? I know some people flex test skis and each ski design has a different makeup but how do you make sense of the flex numbers? Whats on the stiff side and what numbers are on the soft side? Do most of you just ignore them and just ski? Or are having certain flex numbers important to you?
