Here is USFSA video library example: Adult Gold Moves In The Field: Backward Circle Eights
Not a perfect example, but a good example. However, I notice too that his free leg on his LBO circle wanders a little after the top of the 2nd circle. I think this is common for most of us when we skate on the non-landing leg. We all have superior control on every turn and every edge in both directions on that leg.
I also had my first lesson on Brackets In The Field. I have been trying these from time to time on my own without a lesson and have already developed a BAD HABIT of placing my free leg in front after the turn. Now I will struggle to undo my problem.
When the lesson was over I felt defeated did a little freestyle.
