After reading these posts, it’s really got me thinking.
So far I have had great success with the PR system, however I’ve accomplished the success without mindmapping. To me, it seemed like a waste of valuable time, considering I am having good luck, previewing, PR’ing, superreading and skittering.
I have had really good luck with comprehension, but more comprehension could never hurt anyone.
Reading mgrego2’s post, seemed to make perfect sense, telling me I could be getting not only better comprehension, but also quicker and better activation. I’m going to check out the web sight listed in the post and review the PR book. I kind of skipped over the mindmap section, thinking it was something that I really didn’t need.
Considering the effectiveness of the system so far, add the mindmapping and I should be in good shape (flying faster……r.r.r.r…!!). 
Thanks for the advise and you gotta love this forum.
