If you can't fly to Silhouette meca, try this website on for size.

I was browsing a topic and stumbled on this website.  Good visuals.  Check out hands, head height, follow through, arm position.  I find the videos also helpful.  You need to do some digging and check it all out.  Aspects of Silhouette is good and some video's from the LA State match are great.  Notice the much slower pace of things.
