Cole with Brace here (http://brace.io). We recommend redirecting the apex domain to a "www" subdomain. Note that even using apex CNAME records (Alias records) are still a new idea, and depending on the implementation may reduce reliability or performance.

Here are a few resources from our blog that explain the www redirect approach:
