Moves that were difficult. The ones at the start, the middle ones and the ones we did at the end. Quite honestly it was all difficult. But it was the way the lesson was presented. I don't mean that in a negative way, but it was advertised as "Crazy kicks and capoeira flips" or something. The lesson was basically an over view of the "mad" stuff in capoeira and the emphasis was on having fun! It was a charity event after all. I am quite a strong kicker and find that kicks come quite natural to me, despite my terrible flexibility these days. But I have never really done an art that focuses on or uses a lot of kicking. The kicks we did use are pretty basic; front, roundhouse etc. Most of the "fancy" kicks I did know when I was doing Uechi etc I'd taught myself messing around with friends when I was younger. But that was a long time ago. The ginga. Generalizing, but you tend to see it used in it's "robotic form" more in contemporânea and regional than you do in angola. I also feel that an over use of the ginga when playing is fine for beginners, but not good with more experienced practitioners. There should be more movement or, as you mentioned, a "broken" ginga. You mentioned urban slaves. What were they used for? Actually, rural slaves too. I really don't know much about slavery in Latin America.
