tongue in cheek post as someone who has spent a ton of time on small hill, this all assuming your fundamentals are good, video could show us if that is true or not.
I just want to tell go to Blue Knob make extrovert your proverbially bitch and juptier(which is laughable to even be consider hard terrain) will be the easiest stuff ever.
ski bumps, shun others who do not share your desire
short turn all the time in many different way understand the difference between flex to release and extend to release
learn to pivot slip straight down the fall line first on steep terrain , then on the gentlish terrain on the hill
learn to hop turn, do it top to bottom on steep pitches at your local hill when you can do it top to bottom on steep pitches start finding easier pitches. I use to do this a couple hours each night at HIdden Valley every year I spent there, I can now basically hop turn down 1000 feet of vertical at time if I need/want to. its my get out of jail free card while sking.
learn every stupid human skiing trick in the book.
thousands steps, shuffle turns, one footed skiing, outside foot only skiing, inside foot only skiing, white pass turns, and up and over turns
learn to ski backwards, learn to do it better than 90 percent of you lame hill can ski forwards, my cousin can literally ski bumps backward
do all those stupid human tricks you have learned to do forward now try them backwards, once you can ski bumps one footed backwards I think its safe to say you have pretty damn good balance. I can personally link turns on on foot backward down green terrain, I have a long way to go before I can do bumps this seems out there but all balance improvement will help your normal skiing
go find the small terrain park and learn to at least straight air small to medium tables.
learn what transitions are and start to find every single one of them at every hill you ski on. Learn to pop them, absorb them and pump them
nobody sane ever gets to be truly spectacular at this sport, ski icey bumps and ski lots of them, learn to do it slowly and in control.
I like Q recommendation short radius carvers BUT learn to ski on other skis as well. People who only ski on short radius carvers get way to use to the ski making the turn for them and when the going gets tough you want a ski that you turn and not one that turns you.
by the way as your Sensie I am taken back by the comment "its feels odd to be doing falling leaf by yourself" do you want to get better or do you want to be normal? they are not one in the same. I would take it one step further and not just do a falling leaf but learn to pivot and switch sides with out changing speed or flow.
This is all good advice. Josh, fantastic examples of getting the most out of your terrain.
OP, the motivator for improving your balance is that you will be able to go down steeper slopes and manage bumpier or irregular terrain--you'll start enjoying all terrain rather than just the easy stuff.
Josh, I love your demo. Are you also able to do it without extending through the transition?
