Nice bow John. Here's a couple of tips for minimizing set on your next one. First off even though your limbs are tillered evenly they aren't bending enough near the fades. This is the widest part of the limb and it needs to do its fair share off the work. Also I'm guessing your hickory's moisture level was a little high. You can't get hickory dry enough in most climates (unless you live in the desert) with out a heat box, or heat source of some sort, that go's for most any white wood but especially hickory, it sucks up moisture like a sponge and doesn't like to get rid of it.
