Good idea. I’ve a spreadsheet with every item I would ever carry in the first column and their individual weights in the 2nd. column. Then I have seven headings (and columns) for the main activation types I do. I tick [check] each cell as appropriate to include any item and the spreadsheet automatically calculates the total weight for each activation type. I’ve found this invaluable to seeing where the bulk of the weight is coming from and to ‘tune’ the list for minimum weight.
