What's the point of getting the serve and FH course if you have a t3 inner circle membership?
Speaking as someone who has purchased all three, the T-3 gives access to a lot of stuff.
the FH solution and Serve course are more detailed specific to those movements.
I have only played tennis for five years, but I can tell you as a former figure skating coach:
1.) You can take Jeff's stuff and download it to your HD on your computer. then tape yourself and compare. I have been doing this over a year with my serve and have made significant improvement in my serve. I have some issue to correct yet, but this info have been very helpful.
2.) How many people have you actually met in person on a lesson that can teach a serve. I have traveled to 3 different states over the 5 years and taken a lot of serve lessons. a *few* of them have been worthwhile ... exactly 3 coaches at most out of many who have contributed helpful info, and they only had *pieces* that were helpful. Jeff goes through all of the serve.
3.) I have gotten a lot of good information from Oscar Wegner as well. Especially under the duress of a rated match where I am out-classed and flooded: "find the ball (position yourself and watch the ball closely) "feel the ball" (try to actually feel the ball on the strings) and finish (one of the most important parts of the strokes). I got that from Oscar early and have used it ever since. So if he is endorsing Jeff, that is awesome news.
4.) I am very visual and using video analysis works MUCH BETTER for me than listening to someone trying to tell me how to hit a complicated motion like a serve. The best in person serve lessons I am currently getting is where I stand behind the person, he serves 3, and then I serve 3. He was amazed at how quickly my serve speed came up.
In figure skating many decades ago all of the best skaters in the world trained in just a few locations, they all were on the ice at the same time, and watched everyone else. The imagery went automatically from the eye to the muscles. Why we do better after watching days of grand slam tennis on TV. You can't help but get better watching the best!
So that is my case for visual training with videos. I can spend hours on my computer watching, then tape myself, which will get me much more ready in a week, than an in person lesson or two. I'm not saying that I won't travel to take an in person lesson with Jeff, as I would love to.
How many people do you know who have been in the top 100 of men pros who offer to take videos of themselves and give them out for almost free. Cost is minimal. Oscar was a very talented player as well. Health Waters is only the third person I know of with high ranking credentials besides the two previously mentioned who give away so much great information for pennies!
From my experience, it is a great deal to get a lot of tips that other coaches don't even know about, let alone teach. And, I personally like the idea of small clips so that I can work on just portions of stuff. I used to take a long list of stuff to the court to practice and it would take me 2.5 hours to get through my list of drills .... Jeff's site has a lot to offer and if you subscribed for just one year and did everything on the site, how could you not improve? Heath Waters has a great site as well. But there are very few out there who really know what they are talking about over the entire scheme of tennis, not just a stroke or two.
P.S. Jeff, Oscar and Heath are *all* on the same page as watching the best and imitate what they do. I can't tell you the number of coaches I have had tell me "you are too old to play like a pro" "you can't play like a pro so don't try to" blah blah blah. Figure skating is a lot more dangerous than tennis, so anyone with a brain would watch those who did well, and kept their eyes off of those who did not just out of self preservation! I brought that same philosophy with me to tennis.
