Opinions vary but I like the feel of a lower bottom bracket. My last bike I lowered mine to 85 mm (for 680 wheel/tire diameter and 175 crank arms). No handling quirks and I have yet to drag a (clipless) pedal The chainstays and down tube gets longer which allows a bit more bottom bracket sway for the same gauge tubing. If using lugs you may have to tweek the angles to fit the tubes into the sockets.
