Most guys pull back to see air bubbles, that is not needed and will cause over due stress over time. so a nice gently pull back does the job just fine. Also needle size, i find half inch to be perfect for delts. bies, tries, pecs. Using a 1 inch is ok, but you can tend to go in much deeper then needed on these particular muscle groups. Just my two penies on it. over all very good well thought out post.
