Never just ride down the mountain. That's both boring and unproductive. If you are not building towards a trick, you are wasting valuable track space. Getting a ridiculous high score in SSX means you have to pull a lot of tricks cleanly. So don't try to do a double backflip up an incline -- but do try to never waste time not tricking.
I'm confused as to what this tip is in reference to when playing SSX. When I'm racing, I am not going to spend time doing tricks. Yes, any time I hit the air I will build up my Tricky meter (and I might even begin the race trying to do solely just that), but once I have unlimited boost, I'm trying to find whatever the quickest line is, even if it's somehow through the air.
If you're referring to trick events, I don't see who DOESN'T really take advantage of this "tip." I don't think people ever run through big jumps with no attempt to pull off tricks.
