Bummed out when I can't seem to do tricks on new features

So I've been skiing the features at loon quite a bit and I recently learned kfeds and 450s out I got 450s out of the flat box like almost every time, to the point where I can atleast get the spin good at first and I can kfed on the wide tube rail that you ride up the side of it to get onto. This is my second season on skis so I'm pretty stoked I was able to get them on some easier features and when I went to Sunday river today which recently opened the rails in t72 I was really looking forward on trying them on some features there but for some reason I feel like I got stoked out or something. Like a lot of the features had really weird lips onto the rails, almost like they built small skateboard quarter pipes onto them instead of cheese wedge type lips and when I'd try to come in quick I would just get popped up high and slam my skis on the rail and just wasn't able to really get any of my good rail tricks on them. I'm not sure if I need to practice more on smaller features first then take them to harder ones. Part of me feels like I'm used to the perfect loon rails and the sort of sketchy lips onto the rails messed me up but idc I wanna be able to nail those tricks every time. To get a sense of how these lips are up to the rails I literally back flipped of the side of one several times. But any tips on how to get these tricks to bigger features, just feeling bummed out.
