Uh oh....
LCC = Lightsaber Choreography Competition. I could post probably a hundred or so ones that are really good, but I'll limit myself to maybe 5 or so. Just search YouTube for LCC. There are some really bad ones, but usually 3-5 standouts each year.
Seen the first and last one you posted. Didn't care much for the first, but the last is amazing (IMO). Some of those other ones look interesting. I will have to watch them.
