i realllllllllllllllllllllllllllyyyyyyyyyyyyy like the "*DungeonSkiller" from powerbot its free and gets some of the best woodcutting and fishing xp i have ever heard of.. i dont have much experience with the mining part of the script as i havent run it long with mining on, but im getting 60-65k fishing xp (at lvl 78) and 35k woodcutting xp (at 89 woodcut) COMBINED hourly. Thats quicker than powerfishing/alch fishing ottos grotto doing it legit! The bonus 8k hourly atk xp doesnt hurt, but since it defends itself its not currently lvl 3 skiller applicable. Hope this helps
EDIT: *DungeonSkiller , the * is actually some weird "E" character alt but shows as a * on these forums for some reason. you can find it on power bot if your interested
