rules in combination attack

[inoo]

in my experience, no ruled oclHashcat is more faster in slow hashes
so I think below command is suitable for truecrypt hash

combinator.bin dict1.txt dict2.txt | len.bin 12 50 | \
oclHashcat64.bin -a 0 -m 6211 container.tc

ps) It could specify rule(s) in oclHashcat phrase ( -a 0 -r best64.rule -r behind.rule for example ) if you need
