This is my list of arts. there are some obvious one but it seems like a lot of these are not worth keeping. what would you scrap/send/keep thanks

If you are not attacking somebody,
probe att/def/cargo scrap, positron clouder scrap (if not hacking people). someone might be interested in positron clouder though
The rest I would most probably keep.

I have more cargo then ill ever need so i just keep all of 'em.
