I.m Reijer from The Netherlands, I’m started doing the Windworks course for a while but always fall back to my previous way of playing. I did analise myself again after Greg’s video where he told to bite the finger and put the bottomlip more forward. When i did this i also did my jaw more forward so my airstream lifted more upwards. I’m a downstream player and always wonder if i have to move my jaw forward to get better results. As you can see on my members photo i blow much downstream. Does anyone have any thoughts on this?
