I have a Gaelforce comp line that has been cut to 66' and 886 grains and is still in decent shape. I have used it to add different driver sections to the back of the line to test for length and weight on my comp rod. However, if your rod will "handle a NCWA 8/9 easily" this line might be a fair bit too heavy as is, even with the 10wt tip. But, you could cut it from the back to match your rod like these lines are designed to do. I'd sell it for $80 shipped to the CONUS. Shoot me a PM if interested or you have any questions.
I see you're a shvingger too!
