Point taken, But I was speaking in jest, as to the charge weight it's 44 Kilo according to the people who designed built and commissioned it although I have know idea how they came up with that figure I asked for the original spec he was working from and the response was " well it's a estimate really" with that kind of proffesional attitude I think I'll go with a little at a time till I get the SC & SH where I want them.
