Replying to What are the downsides to Quiver Killers?

So next year I am looking at completing my quiver Gonna buy a 105 ski and a 116 underfoot. I also want to get into touring. Are there any downsides to putting quiver killers in them so I can use them for regular alpine and touring as well? This way I would only have to buy two skis and one touring binder and switch it between them. The only downside to this that I can see is putting two sets of holes in a brand new ski, as well as some potential conflicts with mounting positions between the bindings. What other negatives are there?
