My favorite worm to throw is a 10" Power Worm....but lately I've been using some 14" & 16" Mann's and Gamblers..... I've never tried the multi-hook method....not sure I know exactly how to rig it.
Any advice out there....'cause I'm gonna drag one around Lake Fork ALL DAMN night Thursday....just sayin'.

Not sure about the multi hook, bit I use a 5/0 Trokar TK130 for 10 inch PW, seems to work just fine.

Need to be throwing them on my Ledge Monsters. 6/0 hook for your 10" worms and 8/0 hook for your worms bigger than 10".

Owner and mustad have oversize worm hooks. I've never had an issue with a large 5/0 on ol monsters.

5/0 Owner J hook works well also.

6/0 Owner is what I use on Fork most of the time. But never have had a problem with the 5/0 either.

I use my same ole 4/0 round bend offset worm hook up to 10". I have a 5/0 I could use for bigger worms. Bass eat most meals head first and even if they don't, they don't have a problem getting a big worm choked down. I've caught 4-6" kentuckies on 10" worms with the worm all folded up in their mouth. The big key is a wide enough gap to get all the way thru the plastic

You don't need some crazy multi-hook set up for a big worm. I've caught 14" fish on a 12" Mag Old Monster and a 12" Kriet Tail Worm on an Owner Wide Gap Plus 5/0 hook.

A wide gap hook in the 5/0 to 6/0 range is plenty for a big worm.

5/0 Trokar. Never had a problem.

I didn't know that you catch 14" fish. I thought you just caught bigger ones. LOL

5/0 Owner Jungle Hook. Never had an issue on 10" or larger worms.

5/0 Owner offset, wide-gap

The first time I ever threw a Zoom Mag Ole Monster was at the RR bridge at Monty. I rigged it up T-rigged and showed it to Khristian. He laughed at it and asked me what I planned to catch with it. I said, "Just sit back and watch!"

I threw it out. It hit bottom and I got bit. I set the hook and reeled in this pound & half fish. We both got a good laugh outta that!!

Caught a bream barely longer than my hand several nights ago on Texoma with a 10" worm & 5/0 hook. Little dude had engulfed all but a few inches of the ribbon tail and was hooked way back in the top of the roof of its mouth...less than an inch of the shank was out of its mouth. Still amazed how it got all that in its mouth.
