Through experimentation I've noticed that the only host cache that actually gets me connected is router.limewire.com. Limewire tries to use these others also:

connect1.gnutellanet.com:6346
connect2.gnutellanet.com:6346
...

I've also tried these others from the Wired P2P pages:

nova.yi.org:6346
gnutellahosts.com:6346
cnet.ath.cx
cnet2.ath.cx
...

Where can I find other host caches so I can find a different selection of files than what I usually find on average?
