FUSIBLE LINK WIRE for winch?

Circuit protection for the winch is difficult. The max amps for most winches is near the max output from the battery for a given instant. So if you fuse to save the winch and prevent a fire, you may blow a fuse, circuit breaker, or fusible link when using your winch under heavy load conditions. With properly sized circuit protection if the battery is cold, or less than fully charged, or old, you may not trip the protection anyway.
I believe that a careful install coupled with a properly rated disconnect near the battery is the safest solution.

On the Warn 9500TI The full load Amp draw is 425 and No load is 47.

Most starters pull less than 300 amps under the worse case conditions, but they are not protected by fusible links.
Most alternators only put out less than 200 amps under perfect conditions. Back when fusible links were common most alternators only put out 100 amps. Even then, most cars that used fusible links did not protect the alternator output (or input for that matter) with fusible links.
Personally, I would forget the fusible links. They provide no better protection, in no better way, than other solutions. They are just harder to implement, harder to diagnose, and harder to field repair.
If you insist on fusible link Bussman still makes quality fusible wire in rolls. They also make beautiful ANN style fuses in ratings up to 750 amps. I personally think circuit protection in this application is impossible to get right. Too small and it creates reliability problems when winching. Too big and you can still have a fire in the event of a short. The problem is, under certain very specific conditions, the two overlap.
The $20 1000 amp, trail tested disconnect was too much for you?

The thing to fuse, IF you just gotta have a fuse in the system would be the solenoid. The solenoid operates at a much lower amperage than the motor and could be handled with a traditional type fuse or fusable link.
