Topband: Radial wire

[Jeff Draughn]

I’m looking for suggestions for radial wire that will lay as flat as
possible.  I realize that’s probably what everyone is looking for, however
I have used the wire from the big box stores THHN etc. and it always has
that permanent curl to it or permanent for a good long while.

 Anyone know of anything that is very flexible right out of the gate test
lead wire comes to mind but probably too expensive.
Thanks
