Sounds like you found your confidence for the rail, plus skipping a lot of the rail looks sweet if you tweek it right. I do the same with a rainbow rail I. Skip the first or last half of it with a tail grab. The only problem I have been having is with the box set at 45 to the horizontal as you approach. I do a lot of ass sliding on it the whole getting myself to the same angle after the approach is still a 50/50 for me. I would also say just jump over the rail a couple times to get a feel for it and follow someone in who knows how to hit it. Then just hike it till you get it, or just lauch of the ramp and tail tap the last part of the rail and look cool.
