the normal revivals are not symmetrical, http://www.evo.com/outlet/skis/k2-revival.aspx
they have the 121-90-117 as well.
to the OP I ride the revivals now (or did, depending on the condition of my core after my binding break) and they do well in the park but they aren't really that poppy, but they're still a really fun ski. I've ridden then about 15 days and I do have 1 edge crack, but that's about as bad as it gets. The revivals shred virtually everywhere even with rounded edges, and fly down groomers like no one's business. they would be a good choice, but if you are going for a mostly park ski I would go with the domains, which are a more buttery, symmetrical, ski very similar to the revivals
