The last three tournaments I've bowled, Mike Fagan has been on the pair next to me. After all the time off, it's amazing how sharp his game still is. He's backed off about 100-150 rpms or so, and it's amazing watching how powerful his ball still is when it looks like he's doing absolutely nothing to it at the bottom.
Stu, has excellent control of what he does with his fingers at the release. He has very powerful grip strength, and relies on timing and "fingers" to shape his reaction. I love watching him bowl. He's like a modern day version of Norm Duke, versatility wise, IMO.
