There is a thread under the F18 section of catsailor that talks about this a bit. Should be easy to find although its not Tiger specific.
I've been looking at one of the 5mm spectra double-braids, to pull the core out on, but a good friend has used a Dyneema blend Mafioli with a dyneema section spiced from the head to the halyard block. Said it was much simpler to make, doesn't have twisting issues, and is still friendly to the spin, preventing burns.
