I have. Speed reading didn't work that well for me. I bought the books by Tony Buzan and the Evelyn Wood program and applied the techniques. I didn't get much out of any of the techniques in the way of comprehension.
I do apply the techniques I learned from those books to Photoreading in the activation stage, especially if I'm rapid reading.
I'm sure the Buzan and Wood methods work well for some people but Photoreading is what finally got me to where I wanted to be.
