Staying Current During Winter in General December 17, 2014 Brian, this is a great article and some really good suggestions to stay current over the winter. One comment though -- as a climber, I've always been told never to clip metal to metal, if there will ever be fabric attached to either of those things. For example, on a quickdraw, one carabiner is always the "rope" side, and the other is always the "wall" side (where it is clipped to a piece of metal on the wall). The idea is that the "wall" side carabiner can get worn, get burrs, etc., and you wouldn't want your rope rubbing against that.I think the same concern is at issue here. If you clip carabiners directly to the large ring -- and then swing around in your harness over and over -- you are risking introducing wear to that large ring, putting burrs in it, etc. Your risers will then be rubbing against that wear/burrs/etc. and this could potentially cause a failure of the riser. Perhaps you could use risers properly installed on the rig and clip the carabiner through the top of the risers instead, where the metal-on-metal wear wouldn't be an issue?
