In SL I started to use significantly shorter ski poles. By doing this I feel I can ski closer to the snow. It dropped my CoM. Also, I dont need to lift my arms as high to plant my poles. It also made my ski pole work quicker.
I also got new boots with shorter boot soles. This improved the quickness in my leggs and how fast my skis react to any movements I do. The difference was quite substancial. Especially in SL it seemed to have the biggest impact.
I dropped my canting back to cero which works much better for me on steep, icy, fast racing tracks.
Ive moved my boots slightly forward of the centermark on the ski. It makes the skis turn more even and it prevents skidding. Now its much easier to hold a carve.
I use more narrow boots now. Since I started using semi racing boots aka Doberman 130 its much easier to carve since I dont boot out anymore.
