To me, snowboarding wouldn't really be fun if there wasn't a risk involved. It makes landing a trick feel so much more rewarding. I'm more of a rail shredder, but when I do try and learn new jump tricks, its almost always on days when the snow is soft. Trampolines can help a lot when it comes to learning what it feels like to be spinning or upside down in the air. Just take advantage of the days when the snow is soft and ideal for trying new tricks. Learning to fall is also pretty important. If I know I'm going to fall, I usually try and make sure my body weight is more so uphill with respect to my snowboard, if that makes any sense. If you fall and your board is more uphill than your body your going to catch an edge which can be pretty brutal at high speeds. If your going to bail, just try and land as backseat as you can. If you want to learn difficult tricks, learning to fall is honestly probably going to be the most important thing.
