Things to note: Raid groups grow from left to right vertically. The unit frames to the right of raid are MT's, and below the raid is Assists. Currently using MSBT and missing Parrot. The memory load includes the non-LoD version of Lightheaded which runs at 14mb...so subtract about 13mb from the total, so the entire UI runs pretty light. There's actually 4 fully active keybound bars usable, just not visible...3 of which display as paging modifiers on Alt and Ctrl. Probably most happy with this layout...as I've gone through quite a few in the last few weeks. Tooltip borders are custom loaded to replace the main blizzard tooltip.
