While considering that the number of requests to our time servers will
grow over time since the client decides which server to sync with.

some of the more heavily, higher-speed servers? or do we want to keep a
setting where we serve fewer clients with the highest resolution of time
given specific setup and let the client queries grow from there? I
suppose this also takes into the smart dns load-balancing that goes on
in the background.

What do you mean by load-balancing? NTP cannot be load-balanced. NTP
does a lookup and gets a specific address and continues to use it every
poll interval. If the server is unavailable then it doesn't matter since
it also queries other servers and decides based on a number of factors
which is likely to give the most accurate and precise timestamp at that
moment. That changes as traffic, network congestion, availability
changes and NTP will dynamically choose a different source for time. If
the DNS has a number of addresses associated with a fully qualified
domain name then NTP can take advantage of that and use all of them if
you use the pool configuration option.
