I clip a single bungie from a bridal wire to a line i have tied on both diamond wires to prevent my lines from getting fouled.

This works 95% of the time. It is important to make sure you have a line on both diamonds so the bungie can slide as the mast rotates (otherwise it puts some "pull" on 1 side of your diamond wires and not the other.)

I use little plastic clips on all 4 ends (2 on the bungie, 2 on the diamond wires) for easy on and off...
