I am 100% trad, and this is what I have:
Unger belt, on which I hang my bucket on a belt, scraper holder with Unger ergotec scraper, and I tuck 3 scrims/microfibre cloths over it or carry one over my shoulder. I carry 3 squeegees (one in boab and two in my bucket. Obviously I carry my ladders as well! I have a selection of trad poles and a couple of A frame ladders in the van, as well as spare consumables (cloths, squugee rubbers, scraper blades etc) and a barrel of fresh water. I've loads of other stuff too, for gutter clearing etc.
I also have a rug that I use for wet decking etc.
Funny enough, when I'm walking along, my boab and scraper holster hitting each other make quite a rhythmic sound!
