I bought all the kit at the start. I think my works okay, but i'm slow. I was good with a pole on ups because i didn't see any need for ladders. I still sometimes do cons roofs this way and finish wfp, but I was never able to use larger squeegees properly.
I've seen people do that s maneuvre, and people doing shops like they're in a ballet.
My favourite trad tool is the rough applicator, ungers is green. I only get this sort now, I would love something similar on the back of my wfp brush.
When I first came on this forum nearly all the threads were about trad- then there were the trad versus pole rows, but you don't even get that now.
