I ran a weekly handicap throughout my state for over 11 years, plus a scratch one for the last 2 years. Here was the problem.
Many higher average bowlers scream they wanted harder shots, but when I put one down, most of them did not show up. Now why is that ? Well, if you average 230 on THS and then I put down a much more difficult condition and you are not getting many pins, you can not compete with the handicap bowler that rolls the ball straight down the lane regardless of the condition. You would think that the higher average bowler would make the proper lane adjustments but in most cases, NO. Lets face it, many bowlers average high because the center where they bowl puts down a high scoring condition. They use the same ball and stand in the same spot on the lanes every week. Thus inflating their average and their heads.
In my experience, higher average bowlers like to complain too much. Shot is too easy, I can not compete or the shot is too hard and I do not get enough pins.
My advise to all the higher average bowlers is try to bowl in scratch ONLY tournaments and if you do try to bowl in a Handicap one, just put on your shoes, bowl and stop complaining. Lets face it, the tournament director did not force you to bowl in his tournament, that was your choice.
