if you slay more rails then jumps then get the Domains. they are the better rail ski of the two. But if you like to kill the jumps and hit a fair amount of rails then go with the revival. the revival is a better jump ski that is more made for big kikers then the domain is. they both have k2's new jibzone so they butter pretty easily. But if you slay rails a then get the domans if you like to kill the jumps get the revivals.
Revivals can be bought either flat or with schizos and the domains only have flat option. So both skis can be mounted with bindings of your own choice.
Both skis are good in park, but as earlier mentioned, if you hit more rails and smaller jibs then propably get the domains.
