I have 800-900h and now I have 2 stacks of arrow with me, needle and wood. I did however use fire arrows to take down the second boss and make use of all the arrows found in crypts and stuff along the way up to the mountain.
Then I actually started to make obsidian arrows myself.
After that i mainly have been using wood arrows sins they oneshot most of the enemy from distance anyway and either Needle or Obsidan for loxes and stuff.
I guess i'm a bit lazy when it comes to making arrows :)
