With manual loadsheets the principles are essentially the same. The only difference will be the breakdown for compartments and shape of the trim section.
For example A300 has Cpt 4 split further into 41+42 and then 43+44 on the left side of the sheet. Each company has their own methods of course and an A320 for company X will differ to company Y.
Main issue is learn the principles and cross checks and improve your speed. Its easy in a classroom, but when at the gate with other issues to distract you, errors like going the wrong way on the trim or incorrect amount will be made in the early stages. Always complete two copies as far as possible whilst it is quiet. That way any errors wont mean a complete restart.
