A bit of advice from me would be to have the receiving hand (the dominant hand, you right) to be lower then normal and also less active in "pushing" the diabolo for the throw/release from the string, but trying to keep it longer on the string (more string time, instead of airtime). A final note on high diabolo stuff is this great quote I tell my students; a high pattern doesn't happen above, instead it happens below, that's the part we can control, the catch and throw.https://www.youtube.com/user/ArjanGroe/videos
