I'm LFF and working on 35, running it infrequently.
The turn in with speed has helped my gates the most. With speed you can do a gradual turn in and get your angle set before the boat is all over you, then just hold position.
Be sure you're up over the middle of the ski when you start your turn in with the nose of the ski engaged (as bmiller said), don't fall back to turn in.
I'm still working on turning in with more speed. My mind doesn't like it, but my ski does.
