I would agree that those are good clinics with the coaches being very approachable. The best coaching clinic I've been to, though, is without a doubt the "Be the Best" coaches clinic held every year in Cherry Hills, NJ. It's put together by the Weeklys and no matter your thoughts on them as coaches, they bring in great coaches to speak and talk with. Their format with the "Ultimate Rap" is great and if you are able to go with a couple of other coaches, you can split the sessions and get tons of info. Most will let you video their sessions as well. This year's clinic was this past weekend, but I've gone 3 times and it's worth the cost of plane tickets, hotel for 3 nights, and a rental car. Couldn't make it this year unfortunately. The coaches are great about talking with you and what I thought was really great was that they were interested in what we the TB/HS coaches were teaching.
I got into a great discussion with Coach Drohan, Coach Hutch, and Coach Gasso two years ago about how they teach the backhand..we spent 20 minutes shooting ideas on drills/glove work to improve it.
