Paul,I agree with LaDonna, I have used "Downey" fabric softner in the past, what I did was coil the lines into a 5 gallon bucket, then filled it with a 50/50 mix of warm water and Downey, let it sit for a day, then rinse. getting the Downey out of the line was the difficult part, had to rinse the lines a couple of times but the end result was well worth it.How well does this work (you ask) the first line that I used this method on was a 200' three-strand twist "sisel" anchor rode and we all know how stiff sisel is, anyway after the inital bath in Downey the rode had the same flexability as a double braid line (not exactly, but close enough)just my 2cents, good luckrichj
