Your key is NOT on my key-ring.  Nuff?  Very little in gpg
version 1 to show this stuff.  If you export your key to
a file, you can just paste the text into the web-site input
panel and he dumps it for you without you having to download
and build pgpdump, e.g.,

$ gpg -a --export 2D1FA0AA > JoeMoe.asc
$ cat JoeMoe.asc
# copy and paste into browser panel at pgpdump.net for
# analysis

Do you REALLY want CAST5 as your preferred symmetric cipher
and IDEA as your second choice?

$ gpg --edit-key 2D1FA0AA
Commmand> setpref AES AES192 AES256 TWOFISH CAST5 3DES \
	SHA1 SHA256 SHA512 BZIP2 ZLIB ZIP Uncompressed \
	MDC no-ks-modify
Command> save
$

What you put where and the order is YOUR choice.  Only
YOU know what you want.  No, you cannot ask me for
recommendations but if you dump my key you will see
my choices. Ergo, the order I gave here and the omission
of MD5, SHA224, RIPEMD160 hashes and the BLOWFISH cipher
does NOT mean you should exclude them. The line was getting
rather long there and you do NOT put in the "\" ...
There are short-hand notations for them and Laurent Jumet
posted them a little while back (Volume 43, Issue 17 of
the Digest).  So you can pick your poison of long-hand
verus short- hand as well.  Isn't that nice?
