aha, high stuff, maybe I can help you a bit with that...
I would lower the pattern, that will make siteswapping more easy.. I think, in general, you throw to high. Look again at your 51's, you have enough (too much) time to do the 1, the 5 can definitely lower even without lowering your pattern.
In my opinion you make very big arm movements (a reason why you throw so high), maybe it's a good exercise to throw a diabolo without having your string above your head (now every time you throw a diabolo your arms go up and the string comes above your head).
so, in short: less bigger armmoves! (probably, untaught, your pattern will be lower by doing that).
good luck!
