Did trad for 20 years or so ,two years on wfp now but still have few trad ,use ladder slip mat and lots of common sense . always glad to get back to my WFP after a bit of ladder work AND I can put my gloves on in winter which is virtually impossible with ladder-squeegee work - does scare me though when I see some guy up a ladder over a spikey railing at an acute angle in the wet with no safety precautions -often feel like commenting but have resisted so far ,I am 53 and maybe Im so much more sensible with age - I certainly wouldnt climb onto a pitch roof ,do dormer on one side holding on with one hand , climb over apex and do dormer on other side like I used to do !I got away with it though ,plenty dont.
