I have not played a Stone/Ice Brute (/Ice's armor is too ugly for me personally), but I have a lvl 35 Ice/Earth Dominator and he is a blast to play. You're right about endurance. Also, the levels before ice slick can be a grind, but the play style itself is super satisfying. With that said, I'm not sure that your "ceiling" as an Ice/Earth Dominator will ever reach your ceiling Stone/Ice Brute. Also, if you are playing with two kiddos, you may want to pick a hardy class in case they wipe.
