I’ve never done it on cantis as this was my first time but have recently switched to a disc braked bike.
They were much easier to use than my cantis, lighter touch to get powerful braking so I was able to relax my arms and hands more.
They always worked at all points the limiting factor (other than skill) was the grip of my tyres.
They did wear down a lot but I think I had organics in. They are bb7 and I had to wind them in a bit to keep them working. Pads went from used on the road, burnt in and virtually new to about 1/2 wear.
