theyre completely different, and on purpose too i think. both of the parks are set up by the same people, maintained by people who are friends w each other, and ridden by the same people... more or less. loon is a flow park, its longer so you can get a nice flow run going on. wv is like a skatepark, tons of features all slammed into one small area. depending on how you feel on a certain day either could be better. i personally like loon earlier season and wv later season because it never gets as cold at loon. WV is like a proving ground though, if you can kill everything at wv, youre all set.
