I usually use Cortland Master Braid, which is incredible stuff, expensive but very very good. This past weekend I used 65# Power pro with a mono backing. I was musky fishing all day saturday and sunday and made a few thousand casts (no exaggeration) and usually when musky fishing you'll snap that line with a backlash at least a few times. well with this power pro I never did it one time in two full days of constant casting, and that just never happens, at least not for me. I almost always have at least a few per day when I musky fish. But that stuff is awesome and I'm sold and highly suggest it. especially with heavy baits like musky lures or the A-Rig.
