Been there and done that, it has so many advantages that it should be a no brainer, easily spliced, widely available, lighter in both guage and weight, easy on the hands and body when you end up crashing into it and the list goes on.

The one downside is that I could not ever halt the very slight creep over time. Its very little but never the less I had to adjust the rigging every time I used the boat and by consequence just couldn't get the boat settled to one constant rig setting.

Sadly I gave up and now have gone back to steel rigging.
