Greetings, flashaholics. I see that the AA adapter that was released with the V11R is being described by some sellers as being compatible with the V10R as well. Has anyone tried this? Also, I've heard that the V10R and V10A head are the same, but are they really exactly the same (with some sort of battery sensing feature implemented into the curcuit), such that using an adapter would give you the same output result on a V10R as a V10A?
