You shouldn't have to change the rootserver order. QuickDNS Pro only uses
the root server data in the RTCH resource when it has just been started.
When receiving the first query, QuickDNS uses the data in this resource to
contact one of the root servers and get the latest root server data from
that server. QuickDNS then contacts the root servers as needed, checks the
response time for each root server, and prefers the server with the best
response time.
If you want to change the RTCH resource, you can do so with ease. Due to a
limitation in the template used to display the contents of the resource,
all numbers >128 are displayed as negative numbers (actual number - 256).
However, this is a cosmetic issue, so you can enter the numbers >128
without problems.
