first try at using sleeves on spectra line. 

Use para cord 75, single inner strand
use about 6 inches to make a loop, remove the central strand
use small diameter wire doubled over to feed the line through.  I used copper wrapping wire
heat sear the ends of the para cord.  or they unravel.  A good time is while the wire is in the casing.
Pull the spectra through the para cord and tie a figure 8 knot. 

scientific tests coming in a week or so.  Oshkosh is next week, so I will be busy.   

Initial pull tests opened up a line clip, so it looks good.  I need to borrow a pull test scale.
