Ok, you ask a question, I answer.
I do turn my wrist a little to the inside. Why? Let me explain

Bowling is termed as an unnatural sport, because of many reasons, but because of 1 main thing. The body, arm and shoulder specifically, was not designed to swing back and forth in a straight line. It tends to swing back and to the right (for right handers) and swing forward and left.
Picture swimmers standing, ready to dive in the pool. They swing their arms back and forth to warm up... in fact, you can just stand up and try doing it. You're moving naturally just swinging your shoulders and voila, your arms AREN'T MOVING STRAIGHT FORWARD AND BACK!

Just like theirs!!
Bowling for a long time, we have sort of negated that tendency, since we are taught to swing STRAIGHT back and forwards. Especially also, with huge hips like mine, which fail to "get away" from the ball in the swing, we have to do a little compensation of our own. For you, it comes from the "hip twist" seen in players like Weber and Monacelli. For Ian Wong, it comes from the opening of the shoulder. I don't open my shoulder a lot during my backswing, and the ball flares out to the back and right. By supinating a little, it helps me drive the ball back inside "on line" with the shoulder and target. And in case you wonder "doesn't this mean you would end up with a slight inside out swing since you gotta move the ball away from the hips again" you're right. In fact, that actually helps me because I normally shoot 4 boards left of the target I aim, so this inside out swing actually helps me get back to the target I aim! Killing 2 birds with one stone!
I hope I answered it well, buddy!
