It all depends on personal taste and the environment in which you live or will your bow. Google the properties of polymers and oils and you will learn everything you need to know. Oils absorb into the wood polymers lay on top. I have used a danish oil polymer mix for a hand rub finish that's hard and beautiful. Holds up well against abuse from children but I've never used it on a bow. True oil is easy to apply easy to repair and pretty resilient against abuse. Oils are beautiful but don't have the same protective qualities. Try them all!
