I have been trying this for the past few months, but recently started going back to my old style. It is very difficult to change something after doing it a certain way for many years.  DYDS is something different.  Not just one or two things, but from top to bottom.  I have had success with it, and also failure.  I'm going to keep trying it because I do see a lot of positive change, higher ball speed, less effort...but mastering it is difficult for me. 

I see a lot of merit in Slowinsky's idea there, but I always believe in doing what works best for you. I strive for solid fundamentals as much as anyone; therefore, over the years, I've tried countless things that I've seen, heard, or read about. In the end, it's about figuring out what you can do on a consistent, repeatable basis. If dropping your shoulder works for you, go with it. If it doesn't, go with something else that does work. If there were only one style/approach, the top amateurs and pros would all look the same out there. We all know that, while there are similarities to be seen, each bowler has his or her unique ways. That needs to be remembered and embraced. Again, I'm all for tinkering around and trying to make yourself the best that you can be; however, don't forget who/what you are in the meantime.

I am ignorant about all of this.  Where can I see Joe  talk about this ?
