Only cut your planks if it's the fastest way you can make money (which is about 350k/hr with balloons, mind you.) If you make more money at runecrafting or what have you, do that. I'd just like to throw out Green Dragons and Aviansies as good, consistent, combat-based money making methods. You can make 400k at greens starting at relatively low levels, and it only goes up (I make 600-650k). ----------------- It's been a while since this has been posted on, but I would like to add that I meant to cut planks as a way to cut the cost of leveling, not to make money. So: 50m needed (using the post as reference) Planks cost about 450gp each in G.E., 250gp when cutting (use servant) So, the same amount of planks only costs 27,777,778gp (roughly, and not including servant costs) Using a Clay hammer doubles the exp, so using these throughout (or as much as possible) means you will only have to use half the number of planks, essentially cutting the price by 1/2 more. So, instead of costing 27,777,778gp, it would cost 13,888,889gp instead of 50m to reach 99. (assuming your number was correct) http://en.wikipedia.org/wiki/Opportunity_cost
