I've seen this video before but it's nice to be reminded of it. I must try merging the turbulence today. I don't think I really feel turbulence but definitely feel pressure. Playing with sculling is one of the things I do when the shallow end is full of kids and lap swimming is more or less impossible, I think my left hand scull is less effective than my right hand, but I suppose it's normal for one hand to be less skilful than the other. The same goes for my left leg versus my right where kicking is concerned, I used to jump off my left leg, though, so it should be stronger in some respects. Swimming is full of mysteries!
