Women Kip cast handstands

[ILoveBeamm]

I do straddle cast handstands on both low and high bar. I can do my kip cast handstand without any issues on low bar but whenever I do it out of a high bar kip I arch SO much (i still make it to handstand and adjust my shape when im on top of the bar). I doubt that it's a fear thing since I am comfortable with other skills like giants, so what else could cause such a big difference in how I do it?
