Just going by the very small number I have met, but one guy I have heard can have a bit of an attitude is Low Ki, however he was an absolute peach with me. Took time to chat with me about where the photo I bought was taken, gracious in hearing me praise one of my favorite matches of his, and just a very sweet man. Also Colt Cabana and Chris Hero were class gentlemen when I met them. Not exactly a household name, but C4/sometime Chikara wrestler Cecil Nyx works on the same floor that I do and he is a great guy.
