I have worked hard at not killing the gates and my stack as well, however, often times I am still really fast into 3 and 5 ball (RFF). A ski buddy suggested bending my knees a bit as I come into 1/3/5 and it really worked to keep me in a controlled speed, off the handle a little longer, and riders said I skied back to a stacked position nicely.
My default stack position is knees bent but from video I know I stand up going into the turns and often times end up on my back foot even if the tip does not rise up.
Side note 111* in Nor Cal tomorrow
