Well Kuk sool won's sparring sounds somewhat similar to karate's sparring.In Karate sparring we aren't allowed to do low kicks,but we are allowed to punch or kick to your back.As for the head it isn't allowed until black belt.Then the spinning kicks,jump kicks,and high kicks are allowed, but mostly the high kicks are the ones done because the other two take longer to do so you can easily evade them.Also we are allowed to sweep and trap kicks.So yeah I guess we have some similarities in the way we spar.As for how the style looks, I have no idea.
