One of my best colder water baits is a 4" plastic worm, threaded onto a ball head jig. Mostly a Roboworm or a Zoom finesse worm.                      When Z Man first introduced they're Ned Rig head, I thought this was a great design, with the wire keeper on the hook shank.               I'm not much of a Ned Rig fisherman, and prefer a ball head jig. The best keepers I've found so far are made by Eagle Claw. These have two barbs, upper and lower on the hook shank. They seem to hold a worm in place for a good time, and also have a sickle hook.                 With other heads, I've tried glue with mixed results. I've used Lok Tite gel, and the small tubes of Super Glue. The small tubes of Super Glue  gel dry up after one use.                                           In my last thread on jig worm fishing, WRB mentioned that he used to put ball head jigs in a vice, and flatten them slightly, making them an aspirin shaped head. This aspirin head was made famous by small mouth expert Billy Westmoreland years ago, and known as the Hoss Fly jig, tied with bear hair and later craft hair. I plan on making some aspirin heads for jig worm fishing also.              Another good tip from WRB.                                                My question is what jig heads have you had good luck with, without using glue?  And secondly, if I do end up having to use glue, what's the best glue you've tried for attaching soft plastic baits to a jig head?

I’ve had success with ball heads and darter heads using dead ringers and finesse worms.1/16,1/8 to 1/4 oz. weights all work well in different conditions.

I don’t use glue

Gamakatsu  jig heads are what I prefer for the sharp hooks

VMC Moon Eye jig - aspirin head and a great keeper wire all in one, not to mention some great color combos 😎

 

…and blue loctite gel (though I try to avoid it because it always dries out well before its gone). 

I use the Zman Nedlockz jig heads and the VMC Ned Rig Jig Heads.  They are both similar in design.

 

 No glue for this guy.

 

@Team9nine is arguably the top mind on this subject.  He's a record holder.

I’m using a head with a Victory hook.  I doesn’t need glue.

 

Before that 

I used super glue gel.

 

 

I use these. No glue needed. The worm won’t slide down. You’ll lose the head before the worm comes off

Those  Eagle Claw jigs at Walmart work the best for me also. I also have used some Peanut Craft lures Jigs also they have some unique sizes available for small crappie jigs. And I have bought some jig heads for small 3in or 3.5 in. swim baits also. I haven't used a glue for many years. 

Hayabusas Brush Easy head has a really good keeper that works for every kind of plastic. 

I really like the Outkasts horizontal barbs and Dobyns alternating barn style keepers, but they're rare.

  My favorite keepers are the ones I put on hover stroll hooks and decoy magic heads, just a small loop of heavy mono tied onto the shank, similar to the Megabass Okashira except its mono instead of wire.

A hack fo fishing jigs with single or double barbs, like you mentioned is to thread your wirm on and twist it 1/4 turn afterwards. The cut into the plastic allows the worm to slide off the barb(s) by twisting it you only have solid plastic surrounding the barb. 

I've had good luck with the Decoy Nail Bomb, the Owner Block Heads, and the Picasso Rhino Heads.
