YES Patrick is based at Moorabbin, and yes it would be worth while going to see him about your problem IF that is the area of Melbourne your living in. If your in the northern suburbs area it would be worthwhile going to see Paul Madden at Keon Park he has drilled all my equipment and has spent countless hours working on drill patterns, thumbs and pitchs so that i can get through 8+ games and not be sore or rip open my thumb, he has done this with numerous bowlers out at Keon Park and by doing so has increased there longevity in the sport.
