where are you looking for this thread to go? I'm assuming trick help in that case searchbar there's also a trick tip forum.
but ill add my peice, for rails and boxes its best to start aimed straight at it if its a rail basically split the rail between your legs, pop on and turn 90 degrees so your sliding sideways on the rail, spot the ending and keep your balance (land with more weight on your leading foot) most of skiing is just commitment, if you fully commit at a trick and don't pussy out or half ass it you'll probably land it (at least for the basics)
