I know this is pretty new but thought I'd ask if anyone has used these yet? A 12" worm is HUGE...is that too big? I have some Zoom Ol Monsters at 10" and those are big. I'm waffling between this Mag 12 worm and maybe a Strike King Rage Thumper 10".

Haven't tried the Mag 12, but the Thumpers are proven baits.

I used to think 12 inches was a big worm and now it’s one of my go to sizes

Love throwing big worms. I have some 10.5 inch worms but prefer the 12 inch mag ol monsters. They will catch all sides of fish. 

7,5" is a standard worm, 10" is a good size for most places, 12" is just a big worm that works great in summer. Gambler makes a 13" Ribbon Tail that works really well, also have a 16" straight worm which looks gigantic, but guys actually catch decent quantity and smaller bass than you would expect since worms are thinner than say a big swimbait.

 

Mr. Twister has always had good soft baits, I am sure the worm will work really good. they make that Hang 10 I think its called and it is a good ribbon tail worm. Mr. Twister has some new designs in past few years that are pretty good but never seem to sell. Kind of like how Culprit is really improving again as well. 

 

Mr Twister direct usually has really good deals on closeouts and even the new stuff in kits etc. Really easy company to deal with, I still buy phenom worms and keeper hooks from them every year, and some grubs, sassy shads etc. The Exude line has some good baits for bass fishing as well.
