I used those until I found these:
They're a bit too large but you can cut them down to fit even 32nds:
I've tried every make of weed guard available and prefer these to wire/plastic, hands down. Bought in bulk, they're less than 10˘/each and the time I save tying them/jacking with the wire and plastic makes it affordable, in my opinion.
I'll average 15-20 fish before I have them tear up on me and missed strikes aren't an issue. Notice the jig on the right side in the picture above, the tip of the hook is closer to the edge of the rubber. If you miss a strike, just coax the tip of the hook to the edge of the rubber and it'll hang fish like no other weedless.
Hope this helps!
