The new BD Express ice screws with two clip-in holes.
Does using either one of them have any effect on the strenght of the placement, considering holding force, leverage or shearing of the ice?
Thoughts and ideas, preferences or recommendations from BD?

The Express hanger has two clip-in holes. Clip your carabiner to the
lower hole in most situations. Use the upper hole when clipping two
carabiners to the screw or to reduce leverage on the hanger due to an
outward pull (Illustration 5).

Thanks!
