Very nicely done video! Your frameless technique is very similar to one posted on here some time back by an individual from China. He too brought the tubes over thumb and index finger, but then he spread them apart a bit. I find the frameless techniques to be very interesting, but having busted two knuckles, I think I will give it a pass.
Thanks Charles, it was that Chinese gentleman (his youtube is dannypc2phone) that inspired me. He used to be quite regular here, but left for his own Chinese forums before you came. I'm going to try hunting with this style soon.
