I don't think that is the best way to go about it... For some people they develop their own style, and then try to progress their trick bags. I don't work this way. I learned all the basic spins and flips and stuff without any style or grabs. 3's 5's 7's 9's etc.. and mistys and corks and stuff. I made sure I had those tricks super consistant, and then slowly started to work in grabs. Trampolines are definitely a good way to ease into the more difficult tricks while not being pinned out. Mutes are really smooth on the tramp, and get your body comfortable in more styley and realistic positions. Then it's just all practice, watch the pros and your favorite skiers, and when you see a trick you want to learn, just study it and see how they set it, where they rotate, and how they spot their landings and stuff. It obviously just takes some real quality practice to get better and better. Working on your own style and being really creative and smooth looking is the hardest part. That's where I am now. If anyone knows any helpful hints in that department, let me know.
This style of learning might not be right for you though, 'cause I've definitely had people tell me that I just huck myself and should have worked on style before learning new tricks. I guess it just depends on how you like to learn. Wow this is a really long post, sorry. I'll stop talking.
