Love your chit. Getting on rail is technique, not tail pad. LOL, rail grab is anti rail carve, stall move.
The pic shows too much rippage on front leg inhibiting rail type shred.
Try leaning back, not forward. Once you get that wired, and know the rail, and only then, you can start with more weight on front leg to hold the turn longer.
Practice moving your foot back right before engaging, lean back and just let the left leg pivot it all around. Watch those Knost vids. If you can get past the hand jive and jerky-herky, he shows the old school move the foot back for turns and foot forward for trim moves. You're almost there young jedi.
