I've even seen some really good players bridge using the knuckles between the middle and ring fingers. I don't know about you, but I don't carry a ruler around with me when I shoot pool - much less a protractor. A good stance is balanced and comfortable with little or no movement. The eyes should be positioned vertically over the line of stroke such that what is perceived is accurate.
