Mine is the opposite I seem to do better on open bowling ...First league and disabled bowling from a seated position in a power chair so I feel like a sore thumb. I wish I had made the shot I did Saturday night at open bowling during league play. I have never been able to pick up the 6,7,10 split but wouldn't you know it during open bowling on dry lanes I slide the 6 pin into the 7 for such a pretty pick up. My son and daughter in law just looked at me with their mouths open.
