I admit not being able to quantify it off the cuff. All I can say is 
that power being lost in the braid is not available for spark and 
the loss is significant enough to make the braid too hot to touch in 
a medium sized coil. If you like, I would be prepared to build a 
braid primary and compare it with a copper pipe primary of comparable 
diameter. It would be interesting to get a direct comparison for sure.
Don't ask me when but it will be done.
