sounds like you got ahead of yourself if you're asking for sw10 tips after your last attempt didn't go over so well.
Progress up to it, rather than treating it as some benchmark and then filling in the gaps. In a simplistic form, just get sw7s dialed, sw9s dialed, then go for the 10. It's easy to compromise form and stability for more rotation. This is especially true if you don't have a good foundation of experience behind you to draw upon.
