Anyone have actual experience with weber DCOEs on a slant?

I had a triple SU manifold for a while, but I went with Weber carbs because they are easier to get tuning parts for. I had a Mini with an SU and tuning it to be spot on was a real pain. Also when they get some wear they go out of tune easily. Webers/Mikunis are "set it and forget it".
webers do not wear out - they have ball bearings on the throttle shafts, and every tuning part is easily available.
