love the bumps! there's nothing that will highlight flaws in your base technique more than skiing bumps. it really is an artform that requires years of practice and can never be perfected. but, doesn't mean that it takes years before you're having fun, right?
my hubby and his crew are mogul fanatics. i never really appreciated the bumps until i started skiing bumps with them. they're excited like little kids when they ski them. they analyze every run and talk about things like their hand position and their turns in slow motion lol. but i will say I've taken what i wanted from all that and now i really enjoy skiing them.
don't get too hung up on the million tips you'll get, because there really are a million thing that go into getting good at bumps. instead, try to tackle one thing at a time and don't move on until it's muscle memory.
second, if you take away the bumps, your technique is really the same basic technique that needs to be solid on the groomed runs, but maybe a little more exaggerated and quick. so if you're perfecting your turns and body position for a steep fall line run, you're also practicing your mogul skiing.
next, even though it doesn't feel like it, most people are backseat at least somewhere in their turn on a bump. the terrain is more 3d in the bumps and you have to stay forward on every part of the bump and every turn.
of course, there are a ton of other things that other people have already said, so I'll just leave it with one more. you can totally cheat when you're starting at moguls! one of the biggest things people run into is speed control. but there's an easy way to control your speed while you work on all the other stuff. check out this YouTube video:
it's in Japanese so you can turn down the volume. it's irrelevant. but this side slipping can be a game changer if you use it to slow down while you work on all those other tips you get. when i first saw it, i thought it was a joke because it doesn't look like skiing. but when i tried it, it's like skiing moguls in slow motion and you can work on keeping your weight forward, your shoulders facing downhill, your head up and your hands in front of you. then slowly start carving more and speeding up.
you might get some eye rolling at first, but if you decide to try it, hope it helps! have fun!
