Theres been a few unfavourable posts on here regarding Yougmans (hard on your feet, heavy, unreliable regarding strength)
6 months ago I needed a new ladder for work, and looked at a Youngmans and also asked on here about them; funny, as that week I was at a custys house and they had a Youngmans lying on its side down the path, it had a 10° bend in it along its length!
I bought a Lyte in the end, great ladder.
