Anyone figure out a good way to run your downhaul and mast rotator lines so you can reach them while out on the wire when sailing Uni?

When the wind is puffy I like to be able to make adjustments while staying out on the wire upwind, but to reach these control lines on the hull, I have to come in, or at least sit up half way and bend my knees in, which is exactly what you -don't- want to do when a puff comes on.

I have tried extending the lines with shock cord to my trap line, but I usually end up tangled up when I come in to tack.
