I use brake levers from the mid 1980s. Long before Shimano introduced dual pivots. There is absolutely no way I could have ever adjusted my Dura Ace 7400 sidepull brakes to be nearly as strong as my 7700 dual pivots with 7402 Aero levers. Simply isn't possible.
One of the reasons those Synchrons don't work well is the thinness of the brake arms.
