He's my take & a few items not mentioned already....
I'm a huge fan of the stivot / push / surfer for eastern free skiing. Here's my thought process- the Right coast is tight & often real estate is limited. All mtn charging is a mix of linked turns when the room is available & maneuvers for speed / direction modulation when nessesary for coming out of shoots/trees/funky whales. Being an advanced skier is being able to apply a range of tactics. Love the stivot or 'hi angled surfer cut back' to maintain the flow of a run.
* side note- it's quite liberating to not overthink that every run needs to be a series of linked synchro ski carves!
So how does it happen?
•skill- it does require time to develop any athletic move
•conditioning- yep (not going any farther
•gear- it's a lot easier to modulate w tuned skis/ full race clamps/ hi end boots w non catalogued components
(I learned this the hard way this week when I was demo'ing & pulled a binding out of a ski)
•speed- see for yourself :ever watch from the lift ppl ski a pitch effortlessly skidding & then a racer mows it down at 6x the speed? Go fast or go slow there is no try
•position- all of the above allows the skier be in a posture INSIDE of your skis. Very difficult to creat angles/modulate/redirect if you're standing on top of your gear.
I'll think about it this way (in as layman's terms as possible), nearing the finish of a turn I let my skis continue on the carve back up the hill & I'll transition over em. Skis continue to develop reverse camber / kinetic energy that I'll need. I'll develop some musculoskeletal torsion & then have 3 options for the turn/speed I want once I'm light & need to pull em back to the fall line
•feather the tips to carve em back hard (I push on the shovels)
•push the entire platform laterally
Just depends on what I want!
