For your information, the lanes have not been resurfaced since the end of 92. So yes the heads are bad. So even with the heavy oil, would the ball still burn early? If true, would going to loft be a logical solution (Mika K). The pattern isn't a sport pattern, but it is flatter than any other house I've bowled. Unfortunately those other houses are over an hour away. This house was the toughest last year in our travel league, so I am somewhat pleased with my averages so far this year (205, 209). In case your wondering, I have the highest average in one league and the second highest in the other.
