I have both products and I think DYD is highly superior to the Louis and Copeland book. Like MackJr said L&C are pretty AFC, though still better than a complete AFC attitude.
But the DYD stuff has been a perfect fit for me. It may not work for every guy, but for me it really works.
Regarding the concern about "offending" women by teasing and being ****y & funny, here is what I say: who gives a sh!t? If you do give a sh!t, well then, guess what, it won't work. You aren't being congruent because you are still seeking the women's approval while you are "attempting" to tease her and be C&F. I've always been a bit of a smart ass and after implementing some of the ideas from DYD I feel like I can finally be myself around both women and other people. I really don't give a sh!t what other people think of me. I tease my boss and coworkers, and I sure as hell tease women I interact with. But it is all in fun, and they know it. So far I have not had a bad reaction from a woman, in fact let me tell you, this attitude is about a thousand times better than my previous mindset.
BTW, I'm not trying to sell the DYD stuff. For a lot of people blowing $200 on 11 CDs is too much. For me, it isn't that big of a deal. I'm not trying to brag, it just happens I sacrificed years of my life going to college and working and not having a social life to be where I'm at today. With the concepts from DYD and this web site, I'm finally starting to have the social life I've always wanted.
Plus I feel more like "me" than I ever have (but that is due to quite a few things, not just DYD.)
