This is the set I use for Catastrophe:
Very similar to other sets posted here, but I am able to use a Pole grip over a Rose strap due to my TP set. I'm still waiting for SE to come out with a "beats all" option for hands, but until then I'll stick with Onyx as they are not worth selling.
When Grim +1 came out I thought for sure it would be the best body for Cata, but as stated above attack is so easily capped nowadays that Twilight is the clear winner.
5-hit TP, Aftermath up: (Armadaberk with STP+6 DA+3 Subtle Blow+5)
