The solution really isnt all that complicated or expensive. Just restrict bowlers to 2 bowling balls for a league (house shot) and 3 bowling balls for a tournament (sports conditions). Brings it back to a more even playing field, ie individual skills will become more important then the ability to "buy" and bring countless balls. It may also force the ball companies to develop better all round balls
I would expand upon your suggestions as follows:
1. All bowlers are allowed to use a maximum of two balls on a THS league. One of the balls must have a plastic or urethane surface. Note this restriction also applies to the practice play component of the league.
2. In the event of one of the two balls being damaged during THS league play the ball can be replaced providing it is of the same surface of the original ball. In order to be classed as damaged the ball must sustain an indentation to the surface on the ball track or cracked finger / thumb holes. Note: Damage to surfaces not part of the original ball such as inserts do not warrant a ball replacement (Duty of care falls on the bowler).
3. All bowlers are allowed to use a maximum of three balls on a Sports pattern, if that pattern is listed on the allowable sports patterns on the TBA website. If the pattern does not appear on the TBA website then it will be classed as a THS and the two ball restriction will apply. One of the balls must have a plastic or urethane surface. Note this restriction also applies to the practice play component of the Sports league.
4. In the event of one of the two balls being damaged during Sports league play the ball can be replaced providing it is of the same surface of the original ball. In order to be classed as damaged the ball must sustain an indentation to the surface on the ball track or cracked finger / thumb holes. Note: Damage to surfaces not part of the original ball such as inserts do not warrant a ball replacement (Duty of care falls on the bowler).
5. All bowlers are allowed to use a maximum of three balls in a TBA sanctioned Tournament. One of the balls must have a plastic or urethane surface. TBA will only sanction tournaments that will lay down a sports pattern listed on the TBA website. If the pattern does not appear on the TBA website then the tournament is not sanctioned and it will be classed as a THS tournament and the two ball restriction will apply. Note the ball restrictions also apply to the practice play component of the tournament.
6. In the event of one of the three balls (Sanctioned) / two balls (unsantioned) being damaged during Tournament play the ball can be replaced providing it is of the same surface of the original ball. In order to be classed as damaged the ball must sustain an indentation to the surface on the ball track or cracked finger / thumb holes. Note: Damage to surfaces not part of the original ball such as inserts do not warrant a ball replacement (Duty of care falls on the bowler).
7. All non sanctioned tournaments will adhere to the THS 2 ball restriction rule outlined in 1 above.
There is a need to determine who will police the above in order that all bowlers and centres adhere to the restrictions. It would need the good faith of the centres to apply the rules to events they choose not to sanction. We also will need to see a visible presence of TBA officials to show that they are checking that the rules are being adhered to. One way is to not recognize honor scores for bowlers who bowl in a league which chooses to flout these rules.
I see a number of benefits from implementing the above policy:
1. Bowlers will be able to compete a little better with those bowlers who have ball contracts.
2. Bowlers will need to practice on TBA listed sports patterns to ensure they know what balls to take to the event.
3. This will put some respectability back into honor scores and also put the emphasis back onto the bowler to develop their skills in the game.
4. Re-enforce the importance that sparing has in this game by the means of the one plastic / urethane ball surface rule.
5. Reduce the problem usually experienced at league or tournaments these days of the ridiculous number of balls in or around the playing or concourse area.
