I went from 60-100 as a full spike ranger. From 80-100 I went Aqueducts (EN) till 84ish, Ithzir (EN) till 91, then finished off on the third floor of Nelemar (TI) where I continue to hunt. All of which was pure cake as a spike ranger.
Oh and I learned the hard way that in all those places you should use a plain 4x bow and an arrow in your right hand heh.
