Replying to Help with f4

Hi newschoolers,
I'v recently been trying to f4 and no matter how hard I try I cant manage to get more then a 360 if that. I can stomp a f2 99/100 times but can't seem to get the f4. I haven't gotten my skis sharpened in 2 years but I don't think that would really matter. every time I try harder to dig the edge in and spin it does close to nothing. Any help with this would be greatly appreciated.

Update: Laced it up today finally. Will a somewhat sloppy f6 later in the day.
