WF4 Sage Peformance Taper made by SA

It's a long shot but I'm looking to buy or trade for new or hardly used and in great condition WF4 first generation Sage Performance Taper fly line made by Scientific Anglers. Here's the box for the SA-made line, which is a pale yellow color:

Attachment 19745

PM me if you've got one you'd consider letting go. If open to trade, let me know what you're looking for in 3-6 floating lines.

Thanks for looking.
Chris

Close, but no cigar. I've got an out of box WF-5-F.

The note that I wrote to myself that is with the line in fly line brief states: "Brand New. It was test cast on two rods for about five minutes each during the winter of 2010. Butt section attached."
