I carry a large a frame, a small a frame and a tele ladder. I use both trad and wfp for differing situations.
I take on work which many dont in this area, and because i dont employ i dont need expensive insurance to cover employees.
I charge extra for ladder work due to the increased risks and time taken than i do with wfp, so it works both ways, however - i ensure its always safe to use a ladder, and use supports where necessary.
as they say, horses for courses
