If you don't use Twofish (which is not yet in the standard) your
maximum keylength is 128 bits. CAST5 and Blowfish are native 128 bit
block ciphers where 3DES is a 168 bit cipher but it's effective key
length is about 110 bits.
You mixed up the length of the public key algorithm with those of the
symmetric algorithm. You can't compare them. A 128 bit public key
does NOT provide ANY security. Even the cracked French banking card
uses more than 300 bits for the public key RSA algorithm.
