Being someone who only bots woodcutting and mining, I've learned a lot about how to get the most out of your WC bots. 
  
Please understand I'm not some random person listing what I think is best. This is what I've learned over a long course of time of botting woodcutting. 
  
The script I highly recommend is available on the SDN located  here

Subsections  
  
1 - Levels 
  1.1 - Normal logs level 1 to 20 
  1.2 - Oak logs level 20 to 35 (or 40) 
  1.3 - Willow logs level 35 to 50 
  1.4 - Maple logs level 50 to 65 (or 70) 
  1.5 - Yew logs level 65 to forever. 
  1.6 - NEVER bot magic logs. 
  
The logic behind this is to not start cutting a tree until 5 levels after it is unlocked, as it will still be too slow. My reasoning for what I said in 1.6 is that magic logs are always too slow to be as profitable as yews, unless you're very very lucky. I don't even bot magics on my accounts with 99 woodcutting. 
  
2 - Axes 
  2.1 - Iron axe level 1 to 6 
  2.2 - Steel axe level 6 to 21 
  2.3 - Mithril axe level 21 to 31 
  2.4 - Adamant axe level 31 to 41 
  2.5 - Rune axe level 41 to 61 
  2.6 - Dragon axe level 61 to forever. 
  
I'm sure everyone already knows this, I'm just throwing it in there. 
  
3 - LOCATION LOCATION LOCATION 
  3.1 - Seers Village [ camelot ] - This city is what I myself call the home of woodcutting. I can bot an account level 1 to 99 woodcutting and never have to leave, provided that I come with all the supplies needed.  
  3.2 - Ban Rates - Contrary to popular belief, woodcutting bots do not have an unnaturally high ban rate. Out of around 60 accounts, I've only ever had 2 temporary bans, and 1 permanent ban which was a long time ago. However, some locations are better for staying unbanned than others. As convenient as Seers is, I recommend finding your own rarely populated trees and making a custom bank path. 
   
Location has to be one of the biggest things to consider when botting, make sure you take it into account.
