Pipes got too big and became a place for pro's only. Back when 16' was the norm, an intermediate to advanced skier or rider could actually have some fun in one. Then in crept up to 18' and eventually 22' with nearly 4' of that being vertical. If you stand in a superpipe like that it feels like a canyon not something to play in. Carinthia keeps a fairly mellow "mini" pipe next to their superpipe and it's always being used. The pipe dragon bit that RA brings up is fair but a lot of mountains did invest in one back in the early aughts only for them to go totally unused once competition superpipes hit 22". It's kind of a shame, smaller pipes can be a lot of fun and are great for mastering edge control. I miss the days when Mountain Creek used to host the US open.
