I have to disagree with Capt. Phil a little bit. The diameter of my spro crosslock is larger than the o ring on the bait, so i remove the line tie split ring and attach my snap. Yes, my snap weighs more than an o ring, but c'mon, it's negligible. If you're fishing hard baits, the fish aren't gonna think" i would hit that crankbait, but it has a snap on it." They probably can't see it. And looking unnatual? I fish with unnatural looking baits (shape/color/action) . Everyone does. And i fish in clear water. Mfr's. don't include a snap because split rings are cheaper. I do tie direct to surface lures, jigs, soft plastics. My $.50 (inflation/covid) ?
