I think it's even more dangerous to use ladders when you have been WFP for years.
Your average trad guy spends more time practicing his ladder skills than a circus tight rope walker.
What I'm trying to say is you can lose your edge, a newbie compensates for this to some extent by being extra carefull, but for those of us that spent years working off ladders in the past, Ok we have the experience, but are sadly out of practice, and need to take extra care.
