We use haproxy. I wrote code [1] that configures it based on Consul to do load balance. It has been running in production for 2 years without issue (tested with consul 1.0.6)
For people wondering why not use consul template, this has benefit of understanding haproxy, and it minimizes numbers of restarts to make changes.
Using haproxy over and has the benefit that if Winkle or consul goes down things continue to work, just not updates.
