Any input?
It depends on the surface inside the cranks and if the area at the corners is OK. Ideally the crank will meet the spindle tightest near the corners, and not be restricted by any high spots in the centers of the flats. If you're good with a file and have small curved files, you can file a hair (and only about that much) off the centers of the flats so the spindle is holds in the corners.
Otherwise the torque is the same or close, since you're not actually making the crank tighter, simply pushing it higher on the taper.
