In case anyone who is speedbuilding is interested, I think the best resource I have ever used, and still use quite a bit, is GREGG REPORTING SHORTCUTS by Zoubek and Rifkin. Although many of the outlines are specific to testimony, there are so many others that are wonderful time-savers. I increased my speed from 110 to 140 when I first obtained the book many years ago. This is an invaluable speedbuilding tool and I urge anyone interested in boosting their speed to try to obtain this book. Although this is based primarily in Anniversary and Simplified, I believe that when you pass the 150 point, you're really beyond any specific version. I started as a DJ writer, drifted into Simplied, and combined both. Aside from all this, the outlines in this book are visually stunning!!
I am very interested in your thoughts about your specific experience in building to high speeds, i.e. what do you find most useful, etc.
