Good work boys.
Obviously you want to advance your skiing, so learning 270s will help that on the rail side and add variation to your video.
With spins, are you popping? A few of the jumps looked backseat, pop off your toes to keep yourself on axis.
Keep your arms by your sides on rails, this comes with confidence on the rails and balance So work on your balance over the summer, on tramps, bikes and balance boards will help a lot.
Core strength which will grow through balance exercises will help in the air and landing.
Keep it up and it'll all speed up the process of getting better.
Props and Peace
