Has anyone ever done aggressive inline tricks on skis, specifically rail/box slides? Examples would be royale/torque slide (sliding on uphill/downhill edges, respectively), makio (5-0 while grabbing the ski not on the rail/box), soul (5-0 with front ski sliding at an angle on the inside edge) miszou (5-0 with back ski dragging on inside rail perpendicular to the box). I know a signature slide of Phil Casabon is that he will drag his back foot parallel to the rail so the ski slides on the sidewall.
Many other grinds would be impossible I guess though due to the fact that skis can’t really lock into the rail or cross over each other during a slide like inline skates can. However some of the more technical aggressive grinds may be possible on boxes or tubes only.
Any other ideas about possible tricks?
