When I first encountered Jogo do Pau a couple years ago I was still in the middle of learning German longsword and various single handed styles. My fencing was a patchwork of different techniques and odd habits, but sometimes that’s just part of the process. You have to figure out what works for you and what doesn’t, and that means trying everything you can get your hands on. That being said, I think it’s a good idea to always approach a new combat system/style with a blank slate and an open mind; even if it seems familiar.
