I've got two pairs of garden variety 1990s Shimano 105 Aero levers that have worked very well with old school calipers; DiaCompe 450 sidepulls, Racer centerpulls and Weinmann centerpulls. Maybe the lever action feels a little heavier than with the 105 calipers they came with but not enough to worry about. They feel at least as good as the non-aero levers those older brakes were intended to use.
