well for me the best way to make money is merchanting and wcing, i used to fish swordies, but only spot for them is port sarim and it takes to long to go bank them and come back, though yews and swordies price almost the same. Oh and in f2p world is always full of macros so u will need hi wc if u wanna beat those. to train melee u should go with lessers in karamja, strongest monsters on f2p, range same, and mage try high alch or crumble undead. well hope it helps, if u have some questions i can help
