O-ring,
"Pointing one index finger in the air and twirling it around"
Don't you have to surface to do that?
Omicron,
"if by using both of your hands to signal something gets you completely out of trim, maybe you need to practice a little more."
I beieve you and DIR Tec Diver are envisioning two different signs. I could be wrong, but I think DIR Tec Diver is thinking of the arms crossed in front of the chest, sounds like you are thinking of them crossed in front of your face. If you xcross them in front of your face, you'll have to be heads up for your buddy to see it clearly.
OTOH, what is wrong with positions other than horizontal? I'm horizontal most of the time too, but there are times I want a different attitude in the water. When I want a head up attitude, I assume it, when I want a head down attitude, I assume it. Sometimes I switch to supine.
