I've always thought about going up to a 15 but i decided to keep it stock gearing during my rebuild, if your sure that 1st is too low i'd say a 15 but if since your in rocks/roots i don't know why anything would be to low...

so you think a 13 would be too low overall,btw have you try those insert like Powernow or Boyesen butterfly that you put in your carb to improve bottom end power,btw i installed a '08 yz 450 carb and it is running fine but would not mind having more low end

Stock on that bike is 14/50. So someone already changed it. Are you sure that it doesn't have a 13 on it already? For tight nasty single track I run 13/50 and most of the time I'm in second and third and first is a emergency gear.
