does this screw have the tapered inner core like the BD screws to reduce ice clogging inside the shaft?
As far as i know it does not. From personal experience using both, you can't go wrong either way, but i enjoy the BD because of the double hanger and the grinder knob.
Nick: It does. I have used these on many a multi pitch and they clear just as well as the BD's. They accept more than one biner too so for a hanging belay they are as versitile as others. These are the best !
