Let me just say that I don't think that asking help will really be of much value. You really need to try them in your own system. For instance, I had the exact opposite experience with WBT HEROs. They were definitely on the dark side for me. When I replaced them with a Nordost Red Dawn ribbon cable, my highs were airy once again. I had never thought them to be dark until I got a new preamp. I think the impedance it the key, although I don't know the relationship. Maybe ask for other Predator users?
