no

for ?? historical reasons of compatibility ?? with pgp 5+ 
the default cipher that will be used for encryption, and also for 
protection of the secret key, is CAST-5, not 3DES

you were quite correct in your earlier post, in your understanding
that 3DES is only an 'implementation' default, meaning that in 
order to be open pgp compliant, it 'must' be included as a cipher, 
even if no other ciphers are


another things that affects how gnupg chooses a cipher is
the option of;
 
s2k-cipher-algo ciphername

(by default, if this option is not used, gnupg uses CAST-5 for 
symmetrical ciphers when no key is specified)
