Staging/Rigging Workbox

It was a good summer so I was able to gear up a bit:
200' of New England Ropes KM III 5/8" rope
CMI RP101 split side pulley
Sterling Ropes Eagle SL screwgate carabiner (aluminum)
12" and 30" nylon slings

The last two things on my list are a Petzl helmet and a rope bag.
I'm having trouble finding a rope bag in the style and size I desire.
Basically this but larger:

Look at fire rescue sites, they generally have a selection at decent prices.
