Your go to knots for 100+ lb leader?

Does anyone actually tie knots on their heavier duty leaders? Or do you just stick with the crimps? I was getting some stuff ready for this weekend and realized I didn't have any crimps (haven't regularly offshore fished in a few years). So ,I started looking into knots I could tie out of curiosity. I found a few things, but I can't tie any of the them . Leader is way too stiff. I can spit out uni to uni knots like nothing from braid to 30lb leader, but it turns into a rats nest with the bigger stuff.
