Because of my preference for light leads, I tend to use my line clips all the time.
I like to think that the initial resistance that a running fish feels when it hits the clip helps set the hook, something that a heavier lead would be doing.
It's also easier to get your bobbins nice and aligned if your line is leaving the business end from the same point on all 3 rods.
Plus, if you have been distracted for whatever reason, a quick glance at your line clips will tell you if you have missed anything....
