Tbh, my style doesn't change a whole lot. Walove is right. If you are riding a chute, a big bowl, or something of that nature. Falling all over the place is going to have more of an impact. Meaning that if there is a weak spot you have a greater chance of finding it and setting off a slide. 90% of avalanche victims started the slide that got them.
On the flipside, if I am out pillow riding, or cliff jumping, I am putting down some good impacts. Of course I should be pretty confident about what the consequences are in that zone.
Back to the bowl or chute. I'll rip my turns in them, but I will not stop unless or until I've got a safe spot.
Falling obviously happens and in some spots you may do it a lot. It comes down to what terrain you are riding and what the consequences are, in a nut shell. There are a ton of variables you got to look at for any day out in the bc. None of it is very hard and of course it gets easier with experience.
