I'm not a fan of Tyler but I do like a couple of the guys under him at RSD.
after RSD and LS split from MM, he's switched from outter game guy to inner game guy, and for inner game I could recommend someone who does that 10x better. He takes forever to get to the point, he farts around with a lot of ancillary non-germane stuff, and he is over broad: the salient data is likely to get lost in the white noise, especially for beginners.
To sum it up is he legit and worthwhile, Yes. Are there better options, Yes.
Tyler started from reading Syles material online..then he met Mystery and started learning from him..
They made some bootcamp/seduction school called 'Social Dynamics', Tyler copied the idea and made his own school called 'RSD'. He focused on money-making. I saw his videos, his vids, they dont involve the mystery method.
Tyler also focuses on inner game.. I hate those vids..cause he doesnt know what he is talking about and mostly it doesnt work.
Tyler has a few instructors.. Alex, Max, Julian, Todd. Julian got banned from a few countries due to his aggressive method. Mostly those guys are good..Todd has over 10 years of experience and Tyler.
You can learn from RSD, but remember they go for any girl..not for the 9s and 10s like Mystery go for.
