baccala,
I understand where you come from. There are no bowlers that I know of that take things as well as I do, because I blame myself no matter what. Last week I bowled and in each of the 3 games I left the entire back row. BAM- 8 pin, BAM 10 pin, BAM 9 pin. I blame myself for those shots.
I think the point of myself and some of the others here is that without the THS they cannot miss out to 2 board when aiming for 12 board and expect the ball to get pocket. You don't have to put out a sport shot to make a shot difficult. If a proprietor puts out a difficult shot that requires accuracy I don't care how the ball is drilled, if the bowler is spraying it around the lane they are not going to score well.
