I do when I need more side roll.  Haven't experienced any type of pain yet luckily, but I've seen it happen to others.

Around my 3rd or 4th week in the first league I ever bowled in I had broken my pinky finger and had it taped up in a splint and then rolled my first 250.  Keep it close to your ring finger for a little more lift. Experimenting is how you learn in this game.

I do it all the time. I started trying it watching PBA pros and good local league bowlers. Once you start though and get used to it,it can be difficult to go back. You get so used to the extra axis on the ball, more length and sharper backend if you try it back the other way you may be displeased.
I personally like the feeling of my fingers off the ball to my target and I think I can do it more consistantly tucking then having it flat on the ball.

tucked, the thing is, i try to let the ball go, rather than rip the cover off, so now that im not using finger inserts, theres nothing is on my fingers... except my thumb that up to this point is pretty much not reparable unless i stop bowling

When a house bowler misses the mark, misses the break point and strike, for many ppl its called a wallshot. When a pro does that its call adjustment

When a house bowler gets his finger stuck in the ball and fall on the lanes, for many ppl its called lame bowler. When a pro does that its called the Machuga flop! ha i like this one.

I tuck on one ball that has a span 1/16 long because for what ever reason unknown to me, I get out of it cleaner. On my regular span as well as a ball I have that is a wee bit short, I get out of it cleaner without tucking.
