Personally, I think the sport of bowling needs the bowlers to stop blaming everything and everyone for why it's less popular now than it used to be.
Scores have skyrocketed since the late 80s/early 90s - fact. We all accept that, so then we try to establish the problem which we feel needs to be solved, and everyone has a different opinion. This creates a multitude of problems in itself, because you will never get everyone to agree.
Forget telling the ball companies to change the way they produce bowling balls, that will achieve nothing for the sport. Keep the current restrictions as they are and leave it at that with regards to ball cores/surfaces/RG and Diff. Plastics appear to be getting brought up fairly often in this topic - forget about plastics - that is history. Bowling won't go forward if you keep looking back at the "glory days" of the sport. Sure using a plastic is more difficult and lowers scores, but let's be realistic - we're not going back to plastics. And even if we did, would it really increase the credibility of the sport? Others may have a different opinion on that, but I highly doubt that it would.
Restricting drilling layouts to CG within 1" of the centre of grip and not being allowed a balance hole is fruitless. It may give advantage to some bowling styles, and disadvantage to others, and that's about the extent of it. It will not benefit the credibility of the sport, and I believe it is more likely to further harm it. Some claim that it makes very little difference to the reaction of the ball. Whether it does or it doesn't, either a type of bowling style will become more dominant over the other, or it will not make any significant difference to anyone. Therefore, what's the point either way.
Once again we come back to what really matters - lane conditions. How many new-fangled technology-over-burdened top of the line bowling balls helped bowlers in the sports series here on Sunday? Looking at the scores, it can't have helped much. Change the lane conditions and scores will either go up or down as desired - end of story. You can increase flatgutter depth - yes, and that will have some effect on carry and scoring, so maybe that could be looked at as well - but the critical factor is lane conditions.
If bowling as a sport is to go forward, it needs to be pushed at every level of the market. Social, social-league, competitive-league, and tournament level all need to be pushed and marketed. Without social bowling you get very few new additions to leagues. Most people that start leagues, especially at a young age, do not go into competitive leagues straight away, they go for the fun purely. From there, those that have the desire to excel and get better at bowling seek coaching and more competitive leagues, and from that tournament players are produced. How does this fit in with increasing the credibility of the sport? In every way that matters most. If all people see and hear are negatives, whinging, bad-behaviour, foul behaviour on the lanes in their local centre, how many are likely to go up to the counter and say "I want to bowl, that really inspired me". The arguement raised over and over again, such as in this topic, is that high scoring is what has destroyed the sports' credibility. What I'm saying is that let's look at the other things too - the things that people actually see and hear. A potential league-bowler wouldn't know that last week George or Belmo or Brando shot 247 average for an entire tournament.
I agree that scoring in many situations has become rediculous, welcome to technology. By all means change the guidelines for tournament and league play with regards to lane conditions, but why bother with the other stuff? If you make it so that bowlers only have one board to hit - you've achieved the aim of this topic - scoring credibility. If you can throw a 250 average by having one board to hit to score, in my opinion you deserve the 250 average. If the credibilty of the sport is to be built up again, just don't forget the other factors like behaviour, unity, and good-marketing. Advertise leagues sometimes instead of some 2 year old kid with bumpers and a nappy with an adult throwing a 14 pound ball straight into the bumpers at your local AMF centre. Show Belmo, Brando, George, Frawls, Cara, those sort of people in the ads to show that hey this is actually a sport and there a side of it apart from throwing a house ball into bumpers with disco lights and loud music.
I am sick and tired of hearing from non-bowlers - "bowling's not a sport", and then having them refer to cosmic bowling. Get some decent advertisments. Who knows, over time credibility might increase.
