For some odd reason I can't find the option for Clapton, Alien or other pre-spun wire, so I can dial in my wraps and resistance. -- Why am i not seeing it? It was there, no?
This^^^Open the Wire Wizard tab. There you can enter the details of a Clapton.
Wire builder, enter Clapton
Then under Core enter the wire details. If you have a dual core then enter both. You can add another box if you have triple core.
Then under wrap enter the outer wire details.
