Do handstands, I thought i was comfortable with dive kongs, but then when i learned how to handstand well, i realized i was extremely comfortable diving to my hands.
Also, you might be slowing down, a common mistake for any movement really, vaults/flips
Handstands help a lot with double kongs, Double konging tables is much easier than dive kong them, double kongs are also probably more safe than dive kongs as well once you learn them correctly.
