I mentioned this in the other thread, but it's worth repeating.
I've been getting a lot out of working through MM's TP book. It has it's faults - typos as mentioned, not the greatest layout, and the CD, while providing examples of the exercises, is not produced in a manner that specifically helps practicing with them.
But despite these annoyances, the information, and MM's general system, have been very useful to me to give me both a structure for practicing, and a springboard from which to launch my own soloing. As well as generating a thumb position practice schedule I particularly wanted to get away from 'chasing the roots' in my soloing. MM's book is not a cure-all for this by any means, but it's got me started on a good path in the direction I wanted to go. Now it's all down to me - I can't blame the book for my general incompetence.
