Best way to make money on Runescape. P2P?

I havent played in like five years, but i always made money from selling sharks and abby whips. i have about 10k unused nats in bank, idk how much they are worth but if you could nat run, you could high alchey the Yew longs or magic longs that you fletch. but you have to bee willing to put in about 3 hours of cutting trees and getting the strings. lol its been 5 years thats all i remember lmao.
