which boy name sounds better?

I am second guessing the name of my future son. He is due tomorrow but suddenly I have heard a new name and I am very interested. The names are Sawyer and Dominic the middle name will be Robert. I was originally going to use Dominic but I when I heard Sawyer I thought it might be a sign because I run a portable sawmill therefore I am a Sawyer. I mentioned it to my girlfriend and she loves it. But it is hard to make a decision now because if we change the name now it will be spontaneous and we could possibly have this child tonight. Thanks for your help
