Replying to K fed help?

So I've been trying to learn k Feds this season, I've got the front swap down and can lock in on the swap 90% of the time but every time I lock in I like choke on the rail and can never pull the back 2 out, sometimes I land switch sometimes I land forward, I've probably landed 10 real k Feds but I can't seem to do it consistently. I'm not sure whether it's because I spin left and slide right foot forward so when I swap and back 2 out it's my unnatural way of spinning. I literally skied my backyard set up for 3 hours straight and I still haven't gotten them on lock. anyone have any suggestions or been in a similar situation? Thanks
