With RR even Perle Hauberk is better than Haub+1, and Grim Cuirass is also mysteriously not mentioned for PDT set (or WS, assuming the lack of accuracy isn't a large issue, it's comparable to/beats Perle last I checked). Shouldn't be TPing in Twilight Helm, but it's a fair choice for WS over Heca, also V helm if the accuracy isn't hurting you.
