Tricks

Aerialists do combinations of traditional "straight over" flips much like trampolinists and divers. Back flips are the norm and front flips are rarely done because more flips and twists can be done easier and more rotation (flip) is easier to get when leaning back on takeoff as apposed to leaning forward. After takeoff, if an aerialist does one half twist (or 1 & 1/2) they would then be flipping forward and usually do another 1/2 twist before landing to switch back to backward flipping to make it easier to land.

Aerialist start with one flip with no twists and gradually add flips and twists in a variety of combinations. One could do five twists in two flips while another does 3 twists in four flips. The twists are done in different flips depending on the trick.

For example there are many ways to do three flips with three twists:
A Lay-Doublefull-Full has zero twists on the first flip, two on the second and one on the third.
A Full-Full-Full has one twist on each flip.
A Lay-Triplefull-Tuck has all three twists on the second flip.

Here are the most difficult tricks I've done on snow:
Lay-Full-Full-Full  - Four flips with three twists
Full-Doublefull-Doublefull - Three flips with five twists

Front Flips
The degree of difficulty for front flips should be further increased in order to encourage aerialists to perform a wider variety of tricks. One of the things that is appealing to young skiers choosing Freeriding is the wide variety of tricks they can perform. Landing backwards seems more practical when performing front flips and they are more similar to Freeriding tricks. More young skiers would be attracted to aerials if, in addition to back flips, we also performed, for example, double fronts with a half or one and a half twists landing backwards. I think these types of jumps would be easier than most aerialists imagine and they would provide a unique and exciting lift to a competition.
