Well done Vicki!
Looks like spending some time with Handscreate helped you a lot. We can talk or type for hours but nothing beats one on one coaching...
It totally makes sense to me with regard to the change in boards. Many people find the rocker between the feet profile a bit too squirrely for their liking and on those firm groomers, I also enjoy both my full camber deck and my Rossi Angus profile like your new board. In addition, a directional board will always handle cruising like this a little better than a twin. Once you get a little better and gain more confidence however, you will like the playful nature of that Ollie Pop, especially in powder or good soft corn snow. For now, I think that Rossi is ideal for your riding style.
As for your stance angles, this also makes total sense. I am riding with my angles at 15/-18 partly because it makes my knees feel better and also because I have a natural twist in my legs or hips. Not sure where or why, but I definitely have a slight left rotation in my hips (something AASI can`t quite seem to understand). So definitely ride what is most comfortable to you. I might suggest trying to widen your stance just a tad now that you have discovered this. Your stance is a bit narrow, and if you can widen it a little without causing pain, it can really help with balance and stability.
I really liked on your blue and black run that we can see the bottom of your board....
This means you are really starting to use your edges more and transitioning to a more carved technique. The progression you have made this year is really impressive.
Some goals for next year to improve even more:
Turn your head when making turns from toe to heel and heel to toe. Currently, I do not see you turning your head much. This is is especially effective for the toe to heel transition. Looking over your front shoulder to spot the place you want to turn to really sets your body up well to make this turn (it also helps you spot rude, inconsiderate skiers who think they they need to pass as close as possible to you).
We will work on your unweighting technique. If you watch closely, you are doing an up unweight to switch edges. This works okay, but a down unweight is better for carving. If you look closely, you will see that you hop up slightly, then switch to the new edge and settle back to your neutral position. Ideally, you will find doing the opposite will feel better and also really help you power through your carve better.
To do this, drop down lower to change edges, then gradually rise up through the turn. This rising through the turn actually will help you power through the turn and maintain edge hold better on those icy patches.
You already caught this, but yes, work on closing that front shoulder a bit to help you with your toe side turns and watch the back hand. While "throwing" your shoulder into each turn is not an ideal way to snowboard, positioning them in the direction of the turn adds a little extra rotational force to help add power to your turn.
We will talk more about starting to use fore-aft movements next year to also help you power through the carves better and make riding steeper terrain a piece of cake.
Greta job and like I said, your progress this season is awesome. Good job. I am still working on some ideas we have discussed via PM and will get in touch with you soon.
