The centre i work at hosted a seminar by Del Warren called "Dealing With The Modern Game". It was a very informative session, with some very remarkable insights and visual explanations of the changes in techniques that bowlers have used over time. The new equipment that was introduced at the end was very well explained and it was fascinating to hear the reasons why certain combinations of core and coverstock are not used. Afterwards, Del spent some time on the lanes with all the pro shop guys and bowlers, and looked at peoples equipment and grips/spans if anyone wanted. A big thank you to Del Warren for his friendly and informative seminar. Definitely worth going along to!
