ITP black water EVOs is offered in the same size. They are 8 ply and really tough.
If you don't need a tire that aggressive, you can look into the roctanes which are also 8 ply.
I've heard good things about the Bear Claws but I've not tried them. I know @scott uses them and he drives like a mad man and they hold up.
Another tire that I like is the Rockabilly from Sedona. Again, 8ply and less aggressive. Not sure if they are offered in 27" though.
