Thus, switching to AES-256, SHA-512 or any algorithm with a big, mean-looking number, will not give you "more security". It will give you a feeling of safety, in the same way that red cars are often believed to be faster. If that's your thing, then, by all means, use AES -- after all, one point of security is to reduce anxiety. But, scientifically, algorithm switching is not necessary. GnuPG defaults to CAST5 and SHA-1 because this maximizes interoperability with older implementations of OpenPGP.
