If I'm not restricted to a crowded WROD I choose to do the following maneuvers on my first days, mostly at slow speed. This will be on man-made hard snow since I ski in New England.
To regain precision edge control on the flat end of the spectrum, and to regain precision fore-aft balance:
side slips
pivot slips
backwards pivot slips
one-foot side slips BTE and LTE
flat 360s
extremely slow purely parallel turns on the lowest pitch terrain available
To regain precision edge control on the edged end of the spectrum (starting low pitch and moving up):
railroad tracks
morph those to round carved turns (if traffic on the trail is absent)
manipulate edging to create turns with different radii (if traffic is absent)
mess around with carved turn completion
*progress to steeper pitches (if no traffic and if terrain is available)
To regain precision control over turn shape on various pitches:
extremely short radius turns down the fall line, in a very narrow corridor, at various speeds, on green/blue terrain
*modify platform angle to precisely control skid/carve ratio and turn shape
*modify turn initiations from pivot-slippy to railroad-tracky to precisely control turn shape
To check my boot alignment and to start building up ankle and leg strength:
white-pass turns
one-legged skiing
For fun:
bumps, if there are any
I normally have plenty of goofy "wobbles" to work out at season's start. Since I started skiing late in life these wobbles may never entirely go away. The maneuvers with the *** are things I'll be working on all season and will start on as soon as the worst of the wobbles are beginning to dissipate.
