mdt is a greate tool, You can create your own Default Task Sequence for Clients Servers!!
Normal i need to customize every Task Sequence that i create and that is so boring!!
Copy the TS.XML
Go to: C:\Program Files\microsoft deployment toolkit\Templates & save the TS.XML File
Rename the TS.xml file. I my demo Ward Server deployment.xml
When you maken now what to make a new Task Sequence, You will see Ward Server Deployment Listed. Freaking Awesome!!
