Women Uprise to back hip circle help

[GymRays]

I have a gymnast who is training Xcel platinum. She has been working on an uprise back hip circle on strap bar and she has it really good and consistent. The problem is when we put it on regular bars she doesn't have the same power and mentioned it feels like, on the counter swing, she going to slip off. Any suggestions or drills to moving this skill to regular bars??
