Just curious here. I have a moderately long middle finger and my index finger is about 3/4 of an inch shorter if I hold all my hand out flat with fingers together. Sidearm definitely comes easier to me and all my early success was with sidearm.
People almost always have longer middle fingers, but I'm wondering if people with a higher index to middle finger ratio are more naturally prone to backhands, while people with higher middle to index finger ratios are more natural sidearm throwers.
If my hypothesis were to have merit, then Arsenio Hall would be a beastly natural backhander.
