Don't swim with those RES!!!
I've caught HSB and LMB on nightcrawlers. CC will take them also. You recently caught a 2 lb bluegill. Might be one even bigger.
If you have a 2lb BG ... why not a 2.5 or 3lb RES?
The knot strength of 6 lb test is not quite 6lbs. Knot type and how it is tied matters too. 40 years ago my father I did some experiments on knot strength using a fish scale. I was amazed that wetting the knot before cinching it made such a difference. We found the improved clinch knot performed best with 6.5 turns I think. To this day I wet a knot with a little saliva before cinching it tight.
