I've given clips a go plenty of times and I keep going back to tying knots. When chasing Bass, Bream, EP, squid and others you tend to get some abrasion near the lure from snags, bushes, rocks or whatever and even wear and tear from caught fish.
If you keep changing lures and never tie a new knot your line will be weakened for sure.
I like to continually tie a new knot with each lure. It's not a perfect system, sometimes it's needed sometimes it not but it's good insurance.
I use a 6-7 turn half blood knot. It's strong and quick to tie.
