I'm still bowling with my broken ring finger and had a decent set yesterday!  Had games of 190, 201, and a 277.  Since i'm using only 2 fingers, there has been a lot of stress on my forearm, but as long as I don't try and force the ball, the pain is bareable.  I have been "fairly" accurate with hitting my targets and with a tournament coming up in a couple of weeks, I guess i'll still be 2 finger bowling for a little while longer.
