I went 3 days to Val Thorens with my new complete board, and i love it.
the only thing is i have only a few rachets to click on the straps, so they are OK but i really have to make sure that they are tight enough.
I found out turning was not so easy, i really have to be a bit agressive (because my low weight i think).
What can i do about that? My stance is in the middle of the board & the angles are the standard 15 & 9.
Take another week of lessons? Because making turns aggresive isn't the right way (but you probably did already figure that out), well, let me say, sometimes you have to turn aggresive but for the most part it has to be fluent
Some extra lessons might help you
