What are some of the better commonly used coil for materials.
PVC is what I would like to use simply for availability.
But from what I have read PVC has a high dissipation factor.

Has any one designed a system with PVC and the changed no other aspects of 
it but to wind an identical secondary on say Polyethylene or some other 
material?

If so what were the results?

How much would my arc out put suffer if I used PVC?
