Wow! I work at the Texas Renaissance Festival while it's on, and we try to keep our combat as period-authentic as possible.
Where did you learn?
I started with the SCA (yeah, I know, not over authentic). But through my associations there, I started learning DiGrasse, Capo Ferro, Marozzo, and Gigante through other outlets, as well as from the writings. I have friends with the Tattershall School. I get a lot of good stuff from them.
