if you are having trouble micro managing and releasing as well as rushing, its not your horse, its you ! believe me, i have had the same issues in the past ! the more you micromanage the worse it will get.
they key is to give her a nice half halt [if she needs it, which she probably does] a few strides in front of the fence and then float the reins at her. when she realises she has to jump on her own [with out you micromanaging !] and you wont be in her face, she wont rush or pull against you.
i like to practice with a line of 2 or 3 poles. get her straight, half halt, float the reins, and put your leg on and stay out of her way =]
