invaders are sick, but i wouldn't get them for 50/50 park/all mtn. they have super soft butter zones in the tip and tail and i wouldn't recommend them unless you are using them strictly for park. if you want a good park.all mtn ski, look at public enemys, the new line moships, the line prophet 80 or 100, or even fujatives if you want a softer ski that can handle well outside the park.
lots to choose from
