Usually I don't like saying stuff like this, but you my dear Gustav, are a fucking idiot. Please refrain yourself from future comments on things you don't have a clue about, making smartass comments and trying to be Oli. Trust me, it's not working for you...
Doing a Clipper with a ball or a footbag, there's no difference, you still have to use the same technique if you want to pull it off properly. If I gave you a basketball and asked you to do a TATW, would you do it any differently than with a football? No, you wouldn't...
Back on topic: NO, it wasn't a joke and I certainly wasn't trolling, I have better stuff to do in my life. ;)
Fist off, just to make things clear, I'm not saying that Macca's tutorial is crap, but he did miss out on a very important detail.
Ask ANY footbager what's the MOST IMPORTANT thing with tricks like Clipper and Eclipse and they'll tell you the same thing I pointed out, which is explained very well in the video I posted and which Macca failed to address in his video and that's proper foot positioning - curling your toes and pointing them against the sole.
Also, ask any footbager about freestylers doing footbag tricks and they'll tell you that this is what most are doing wrong.
Sayonara!
