Some people have added a couple of blocks, on each side, under the tramp, in effect, doubling the length of the shock cord. This may extend the life of the cord, when overstretched, from trips around the forestay or off the back of the boat. I'd bet over time the results will be the same, and then you're replacing twice as much cord.
I do this on my CAPRICORN... It works a treat. I've been on a few missions out past the spinnaker and haven't snapped them.
Give that a go
