Does anybody know a good method to get money on RS?

so i recently began playing runescape again, should i kill blue drags or do slayer.. my slayer level is low but i'd work my way up and all my combat skills are in the 70's.. what should i do for money i need it but not desperately i am going to get 99 wc and people say i should cut yews to 99 but i think it is slow and i'd rather do ivy so since i prefer the fast 99 what should i do for money?
