IMO having more mentors is a good thing. People have different personalities, styles, experiences, levels of proficiency... In life, there are 'things' and/or people that simply touch you on different levels...
Looking back, I was heavily influenced by Ross Jeffries, at that time it greatly increased my insight and understanding of female's behavior as well as overall attitude. At the same time, I reject any patterns or NLP, and although it was initially quite exciting I simply gave up on it since I consider it too manipulative, too immature...
Others didn't provide much knowledge, they were rather simpler and more straightforward styles, but at the same time you can learn a great deal of attitude or approach to PUA from these guys. DavidX, G. Brodski, 60 years of challenge, I don't even remember anymore... All are A MUST, at least in my opinion...
Everybody was excited about the famous 'The Game', from Strauss. Honestly, I opened the first couple of pages and I had to close it, there was just nothing I would benefit from, too superficial for my taste... Tried Mystery and couple others, but they were/are just too fancy for my taste...
... was listening to some tapes of David DeAngelo years ago, it was a reasonably good explanation of fundamentals. From today's point of view it was rather quite simplistic approach, however it is still very powerful - it is sort of as if you come around the whole circle, back to the beginning and started to appreciate more simplistic things, that could be easily expressed as "get a hobby, get a life"...
I've stopped reading PUA and Seduction material some 3 years ago, but as far as I can say GC is probably the most elaborated and most advanced that I've encountered, amazing job. I only wish I had access to material like this when I was 16-18, but that's life. Also spent some time on ROK, MGTOW, no-maam.blogspot.com, Red Pill...
... All good, different approaches, different personalities... When you think about it, the basic fundamentals and knowledge is pretty much the same, just described and maybe applied differently... Learn what you need, study different approaches and attitudes, read opinions of other guys, keep doing things that are working for you and omit things that don't - and eventually develop your own unique style, not just in seduction but in the whole life...
