I've posted this question to all of the bow building forums I frequent (all three of them), and the answers seem to be almost evenly split between Unibond/Smooth-On and Titebond III. I like the idea of Titebond due to the lack of heat curing, but at the same time I can get that with Smooth-On. I'd simply forgotten that Smooth-On will cure out in 24 hours as long as the temp is above 70F which it is in my apartment. I do have a heat box that I made to be a knock down design that I can use to cook a bow within 6 hours. Titebond is certainly cheaper, but I do like the gap filling properties of Smooth-On, and I've always used it for everything on the bow - laminations, backing, handle riser block, and tip overlays. Even though I was leaning towards Titebond, I think I'm going to go with Smooth-On just because I don't know how good I'm going to be able to get my glue lines on the first few bows I make during this new run. Also, I have a supplier I can pick it up from locally without having to pay for shipping.
