Line LB Test for LE Walleye

[West Basin]

This is for drift fishing, not trolling. Cast and retrieve or drift if enough wind.

20 - 30 lb test? I understand the diameter of today's braided and other lines is much smaller than the same lb test of monofilament, but even then, is using modern lines of more than 10lb test really necessary? What about knot strength, similar to monofilament in reducing line break lbs? I've used 8 lb monofilament (6 lb effective line strength with the knot reduction) ever since I started back in the early 80's and I rarely if ever lost a walleye due to line break. Having the extra strength seems logical if there is no other disadvantage, but maybe get even more feel if the line is 10lb?
