re: Your go to knots for 100+ lb leader?

I've used the snell, but I couldn't get it to stay cinched up with 150 lb leader when I was playing around. I'd have to leave a good bit of tag line to make sure it didn't back out. I've tied that many times with 80 and 100 lb.

I admit that I suck at a palomar with regular line, so not much success with that.

Tying back to the main line is what I was really hoping to learn about. We cast at Tarpon and need a ~6' leader. I liked the idea of not using a swivel and tying straing to the line so I could reel it up a bit if needed. No luck with anything i've tried.
