blowfish vs. twofish - help needed

Hi,
I'm studying the twofish algorithm and is trying to analyze the differences
between blowfish and twofish. Twofish is designed by the same company as
blowfish and should be based on blowfish. I can see the structural
differences in the algorithm and to some point understand the differences in
the implementations of the two algorithms. What I really need though is some
official research of the differences between the two and some insight into
what parts of blowfish that twofish has inherited.

I've searched the net for some time now with no luck. Hope some of you is
able to lead me in the right direction.

Try posting to the sci.crypt newsgroup. Thoese geeks will probably be able
to help you with the more technical side to algorithms.
