Don't know if any of these has been mentioned yet, but I have a few ideas.
1) A section for the user submit a video of themself and possibly have one of the pros/coaches pick it up and give some tips per private message to the user.
2) Also maybe have a compare to section where someone could view other pros/coaches technique compared to a posted video of themselves. I have seen this tool at some coaching sessions and it would be nice to have a free version of it somewhere.
3) Also maybe have a matchmaker tool like what is on storm's website, where a user can say what companies they are interested in and fill in info on there bowling style and have it match them to a ball.
Just my .02 for somethings I would like to see on a new site.
