Tyrolia Peak 18 or 15(Deadbolt is probably a Tyrolia Mojo 15 or 14 or something). Don't get deadbolt/peak 12.
And mount -2.5 back minimum(FACTORY RECOMMENDED, AND THEY ACTUALLY THOUGHT IT THROUGH). I mounted mine at -2 and they ride switch amazingly, but for pretty much everything I wish I had mounted -3.5 or so. I think that -2.5 is about center of the running surface, which is where you should mount if you were looking to mount 'center' anyways, it's where is in contact with groomers.. center mounting these would be stupid, they'd still work well but not as well at anything as -2.5 does.
