Hadden's 29 I believe, so if you have good gear and don't mind sitting around for 3-ish hours to make sure you get the camp, you can probably down him easy enough? Assuming you get lucky, anyways.

Edit: So close.

Edit again: You'll make more money in the same amount of time by leveling a Druid, camping Sisters 12-20 and porting at 29 than sitting around waiting for Hadden or Pyzjin in all likelihood.
