when to wax

There are only 2 ways of tilting a snowboard while riding. 1 angulation (bending your knee & ankles) 2. inclination (leaning your centre of mass towards the highback or away from the highback). 

The highback set in the middle will allow a snowboarder to lean (inclination) equally…as in their toe tilts will be just as easy as their heel tilts.  

A highback that is set at an angle towards your toes will make toe inclination easier; and heel inclination harder.  Conversely, A highback that is set at an angle towards your heels will make heal inclination easier and toe inclination harder.
