In terms in giants on Rings I think it is vital that the gymnast does not begin bailing from handstand until they can perform inlocates and dislocates towards handstand position. In other words, do not begin bailing from handstand but rather encourage swinging towards handstand. Build the skill upward rather than starting from handstand. I know this can be a long process however if the gymnast can not build upward then there is no point in starting from handstand as this can incur injuries and bad technique.
It is a better starting point to perform shoulder stand bail into inlocates and dislocates towards handstand.
