^ I just want to make sure I read this right. You started snowboarding because it was cool, but then switched because it got played and skiing became cool? Thats how your post reads, so you may want to check your wording.
Who cares what is harder or more saturated, do what is the most fun. For example, I love skating. It's hard as hell, I've been doing it half my life and I still suck, but it's also fun as hell and I land something every time I get on it. My point, go with your heart, the rest will fall into place.
