It's simple, perfect your technique on the piste. About 11yrs ago I thought I could ski, then I did my NZ cert. Now we spent the whole winter perfecting our technique. We went back to a wedge and worked from there. We only trained using a medium radius turn. The reason for this is that this shape turn gives you time to practice new technique. Now, without going near any bumps for a whole winter, and just working on technique, I then went to Park City, Utah. The bump were a dream. I've never skied bumps like it in my life.
So, while it's fun to 'give them a go' for an average skier, to really get great at them you need to really get your technique right on the piste.
