So to me, Freeskiing is the word to define every thing between Park skiing and big mountain.
Freeriding is big mountain, freeriding = Cattabriga.
Freestyle is park skiing, urban and we could include backcountry.
Freeskiing... not many are actual freeskiers, I think of Candide, JF Cusson, JP Auclair, the list is long but that's my point.
Am I wrong somewhere ? Are those meaning subjective somehow ?
