In videos I usually see the j.236A loop start off of 5CC wallstick. I'm still at work so I can't state any specifics yet as I've yet to practice the loop myself.
My current notes for a particular corner setup has:
5B > 5CC >
6A > 5A >
6A > 236A >
6A > 4B >
3C > frog
(do some mix-up here... if frog hits then go with)
5CC > dash 5B >
6A > A Lobelia >
5B > 6A > 4B >
dash 6A > Baden-Baden Lily
