Question

As a general practice, is it a good idea to use multiple TLDs for the name servers?

How should I choose between which TLD would be a good candidate for being the root server for my NS name?

More Info

I am switching over 800 DNS zones to an outsourced DNS provider. I originally planned on setting the zone names to nsX.company.com, but think it would be best to have multiple TLDs such as .net , .org and .info

Since I plan on supporting DNSSec at company.com I think all the 1st tier Name servers must support it as well.

Part of the inspiration for this question came from our provider UltraDNS. In their configuration screen for our domains, they actively verify and alert us if our name servers aren't exactly:

pdns1.ultradns.net
pdns2.ultradns.net
pdns3.ultradns.org
pdns4.ultradns.org
pdns5.ultradna.info
pdns6.ultradns.co.uk
