I'm left handed, But have always trainded both hands. When I spar stick or knife against someone, I dont see much of a differents. my knife does not care if its cutting a left, or right hand or arm. If a knife is comeing in at me I get out of the way, regardless of what hand its in. Sparing espada y daga will realy help getting the left and right down. I have found that without thinking, even though I train moslty with the right, that if I get into a bind or someone is alittle faster, I will switch to my left.
I remember doing a six count drill with Remy. He was teaching it to a group. He realy started to crank up the speed. So at some point I switched to my left, without knowing. Remy then went to his left hand. Everyone ended up learning the drill left handed.
To me it is more about perception. If you think about it you will screw up, but if you just react, you will counter regardless of hand. Remy would always say "It is the same", everytime I would ask him about right against left. Hubad, palis palis, crosada, and even the disarms are the same. Your just doing them from a different perspective.
