Have you tried rehuff? This is a program that will recompute the huffman 
codebooks for better packing. Over long files, the default codebooks are 
usually fairly close to optimal. On short files, rehuff can usually get 
quite a few percent savings (and sometimes as much as you indicate 
ZIP/RAR gets).

Search the archives for the source code, or wait for the final release 
if you don't have a compiler.
