I'm a Free Rig fanatic.
The fine wire eyes of "specialized" weights should slide more freely than thicker gauge due to friction. As mentioned, you'll want a bead or rubber stopper to protect the knot.
There are also some specialized weights like the Decoy DS-9 that helps the weight move more smoothly and protects the knot.
And finally, if you've really gone down the rabbit hole like me, I'll let you in on my personal secret rigging from Fuji...the company who make line guides. It's micro ceramic guide with an open snap (or ring or normal snap depending on model) and allows you to use any weight. And the weight seems to sink faster giving you better separation. This might be superior in some situations.
As pointed out by others, your need rod tip down IMMEDIATELY after the bait hits the water (with open bail) or immediately after your lift technique. This allows for separation. See excellent under water video on the topic below.
And the Dolive Beaver is the Gold Standard Free Rig bait. The Dolive Stick is also exceptional.
