Zebco 33 were spooled woth 10-12 pound test, usually. I would expect a heavy line on a L/W reel would result in an out of balance rig. The result will be much shorter than possible casting ranges.
I'll have to re-visit the albright knot. I use the blood knot to connect lines.
I've used Trilene XL in 4-6 all my life for crappie and other panfish.
