Ive been riding for 8 years and am quite advanced. Ive been doing park for 3 years or so and l cant 270 on. l can easily 360. and l can boardslide in my sleep but l cant put the spin and boardslide together. l ride regular and my natural spin is backside so l would land in a backside boardslide which is perfect for me....except l cant land it. any tips?

Oh, the old 270 on.
Well, l will tell you, it took me about a good straight five days to get it down.
But some tips are:
1. Keep ur shoulders over ur board
2. When u land, land clean, with ur knees bent.
3. Also, l really do not know how to explain it, but, spin on the left or right side of the rail.
4. And if ur better at spinning frontside, spin frontside, or vice versa with backside.
5. Hope u land it, the trick is really easy once u get the hang of it.
And what mountain do u ride at?

Try practicing doing 360s to 50-50 slides with very soft landings and once you consistently hit those, spin a little bit less and keep your knees bent. Keep practicing soft landings because it is harder to land on the box then on the snow. Hopefully this helped.
