Glad the info is helpul! BTW version 3 of The Other Guide makes the groupings clearer, I hope.
You will be able to use ETTL, FEC and Ratios from your camera menus. If you want to set manual powers with the 430EX, you will need to do it on-flash.
The YN-622C will give you all that the ST-E2 provides, and more. It will work in situations that the ST-E2 will not handle.
Any reason why I cannot at the moment open the guide?
