Depends on the backward compatibility you want.

all numbers for aes 256bit:
-c aes-cbc-essiv:sha256 -h sha256 -s 256  (2.6.10)
-c aes-lrw-benbi -h sha256 -s 256         (2.6.20)
-c aes-xts:sha512 -h sha512 -s 512        (2.6.24)

aes-lrw has a theoretical weakness if you want to store the keys itself
on the cryptovolume.
