Help Choosing HK KK Board firmware version

Ok, little help.... :confused:

So should one always start with the latest/newest firmware version available and test to see if that works, and then if not just work your way down till you get one that works the way you like?

There are so many versions listed in the programmer, I'm just trying to make heads and tails of it all.

I started with, I think, 1.6 for the tricopter, and that seems to be working ok, but just wondering.

Thanks for the help.
