Used 20# P-Line TCB (teflon coated braid) with a 7' Med-Heavy action St. Croix Baitcaster, Abu Garcia Ambassadeur 6500 with titanium 10" leader for trolling.  I doubt I will use anything but P-Line from now on.  Nano may still have the quietness and castability advantage but as far as strength, knot tying and abrasion, P-Line is the way to go when fishing the canadian shield.
