Yes, some of the DIR zone tanks are 14,5 kg but the balance is not like the good old heizer tanks

I found the 14,5kg ECs I borrowed a while ago real sweet to dive with all the lead (~3-4kg, fresh water) as a tail weight between the tanks. This was, however, with about the max underwear I'll ever use (400gram thinsulate & fleece baselayer), so dropping the tailweight for the summer would probably make the set nose-heavy. Lighter tanks would allow a bit more adjustment.
