Would be cool to supplement this with what we know happens to all of these strategies when the load balancer's snapshot of server load is stale.

Inverting this is actually better because it avoids the stale data / herd behavior. i.e. randomly choose X candidate servers and then pick the one with least load. also, 2 may be better than 3

> Best of 2 is good because it combines the best of both worlds: it uses real information about load to pick a host (unlike random), but rejects herd behavior much more strongly than the other two approaches. https://brooker.co.za/blog/2012/01/17/two-random.html
