I suspect Dan and Jay may be on to something in their comments on this previous post. So I've been looking for an alternative rigging for the dry/dropper combo and found the below video.

A trout taking a dropped nymph is one thing, but a carp is an entirely different ball game. I can't get past the feeling that I'm asking for trouble. The below appears to be potentially a better alternative:
