So what about replacing it by Blowfish with 160 bit key ?

Lutz told me that he votes against this, because we can't have values
for each key length.  I know that the keylength can be derived from the
DEK but there is no way to do this when using the cipher e.g. for secring

By the way, is is really required that PGP's strange CFB mode is required
for other ciphers that IDEA?
