Yeah I'm sure I can find a pic. Easier than explaining it
Here is an example:
So it looks like his arms are about 30 degrees in. He has his palms down. I prefer a neutral or more thumbs up grip. But anyway this is more optimal in terms of length-tension. I'm sure I can provide info on that if you'd like.
Also a very good option for RC health and a good deltoid exercise in general is SLA's or "side lying abductions". This is where you lie on your side with a dumbell against your hip (palm toward the hip) and lift the db up to about 45 degrees. There is no scapular elevation that way and it takes the upper traps out of it. Just a good variation to have in the repretoire.
