I've had my copy for a month now and just haven't had time to get through it yet, I'm on the final few pages of the fitting section. I've reserved my own review until I actually complete it, though so far it's overwhelmingly positive and I have no doubts it will continue that way. My absolute favorite thing about both Head Games and now (r)eVolve is that there is zero fluff or filler. They could have made both two or three times the size, with a bunch of pomp and circumstance and arrogance, but these are just a couple guys with a ton of experience that are excited to share what they know. They simply present their credentials, and get right into it. They say so much with so few words, and the best part is they didn't come up with some wild "new" fitting or layout technique, they just explain concepts, present facts and logic, and completely leave the execution up to you with a few recommendations or suggestions. They just present common sense truths.
Whether or not they intended it this way, Head Games and (r)eVolve compliment each other extremely well. (r)eVolve is like doing work at the gym, and Head Games is like the cool down and stretching. Both also have a lot of "replay value." Part of the reason I haven't gotten through (r)eVolve yet is that I've gone back and reread a few things several times. The concepts are super easy to grasp and understand, but as your brain absorbs it all, if you go back and read a section over and over again, the information will hit you in a different way and you'll get more out of it, or see something you didn't "see" before. Also it's kind of a foreign experience to read something that has no fluff and doesn't waste words . . if you find yourself starting to skim, you're gonna miss some important stuff. I'll post my "official review" here in a few days, hopefully I'll have some time to finish it and watch the dvds.
