it doesnt have to be really realistic tell them to 3-4 item it if they can or 1item if skulled bringing some food praying and you'll end up with some good drops but you need good hours of potential before you try (2 at least)
mud staff robin>any melee helm except netz no ammy torso any melee legs snakeskin boots/melee boots obby shield/granite shield black dhide vambs you should stun someone who is air striking you in pvp for potential :)
I may be wrong, but I think the trade limit only affects how much of your drops other players can see; I don't think it affects the amount of items you can pick up. Anything worth over 3k vanishes without anyone else seeing it. Its even more restrictive than trade... Isn't it 6k now since they doubled it? why would they double it?
have saw,hammer,100k depending on planks, noted oak planks thats 4 spaces then 24 spaces for oak planks once you are finished building use planks on butler to bring them back
