Hey guys.
I can't watch the video as i'm at work, my googlebox filters all video streams out, SOB!
My advice on the pass though, is...
-Get the basic action down slowly, and practice it slowly. once you can adequately do the action of the two packets transposing slowly, begin to speed it up a little. Just go with your natural progression speed.
-Practice the invisible turnover pass first. It utilises almost a reversal of the regular passing action to execute the move, so may feel strange at first, but it may help your fingers acclimatise to your original pass. Sounds strange, but it worked for me.
-Do it in 'half moves' once you've got it up to speed. Do the shift of the top packet, but pause before you co-alesce the packets, for a split second. This will help you identify if you have any snags in the execution when doing the final step, if you know what I mean... (if you don't, PM me... i'm not very articulate today!)
-An idea of Zenneth Kok's- practice with 70 cards- once your handling is adequate qith 70 catds, 52 will feel like a dream!
Hope this helped guys.
