If you just keep at it, before you know it you'll be much more solid and secure than you could have imagined! :)
As I said, I do stirrupless and a lot of sit trot every day. I flat 5 days a week and jump once a week if that.
My leg is solid on the flat and I don't have a problem there. I am asking for things I can do to keep it secure when jumping.
