I have spliced many a lines with mono and the Shimazaki-Leader-Splicer-Tool
Shimazaki Leader Splicer Tool - Great Needle Knots!! - eBay (item 260687454801 end time Feb-01-11 21:43:07 PST)
Just need the tool, Zap-A-Gap (or any other waterproof super glue), piece of sandpaper, and piece of mono .
Very clean repair. Might be a little stiff on the glue dots but that is it and it is strong.
Visual pretty to.
