Well, from personal expiriences, (level 87 wc in f2p, all botted), woodcutting scripts are very good excluding the occasional schoolhouse random. I ran a mining script last night-now mining copper, its been 16 hours and I haven't even touched it! Prominer and profisher both work very well, but I think mining surpasses fishing at higher levels (70+ perhaps), but fishing is always going to be about double the profit per trip that coal is, assuming you're fishing lobsters. Fishing is also much easier, in my opinion because of the lack of materials used to engage in it. Regardless, woodcuting scripts have been malfunctioning lately, making fishing the most profitable botting method currently, in my opinnion. I'll let you know once my new miner gets to level 65 or so. I had a level 78 f2p fisher that got banned, but he could make about 400k a day, while my woodcutter at level 80 made about 600k a day, sometimes more cutting yews in between draynor and lumbridge.
