You could always make your own leaders out of a high poundage Berkley Fireline or Spider Wire. These are some TOUGH lines, but, if you really wanted to go all out, you could just use something like a 20 pound Berkley Fireline on your spool.

I landed a 44" muskie on 14 pound Berkley Fireline using a UltraLite Ugly Stick with a Ultra Lite reel. I was fishing for bass, so, I was using my trout rod, but, I saw a big boil, threw on a Mepps Muskie killer, and, well, he hit. It was a tough battle, but, the Fireline held up great.
