My T-rig grubs are usually Yamamoto or Kalin’s 4” grub on a 1/0 Gamakatsu EWG. I’ve been using the VMC “XL” 1/0 more lately, because I like the longer straight shank. 

Gama EWG and Zoom fat Albert all day 

The way @RipzLipz has it pictured is close to how I rig mine. I want the end of the hook inside the plastic to protect the knot. That is why the 1/0 EWG size works so well for me. I'm not about to try to rig it with a much bigger hook and try to get the hook point in a little thin plastic tail.

A curly tail grub on a belly weighted hook was my first 'swim bait'  I still use that set-up on occasion. I've never used them on a T-rig, but I have used 4in. curly tail worms with good results.

Dont be afraid to Bubba-up on a grub and use heavy lines and heavy weights.  

I haven't fished a curly tail grub much in the last little while. Yesterday I was fishing a texas rigged lizard, and I was getting small fish nipping at my bait, so I decided to throw on a grub to see if I could get one. The lizards were green pumpkin, and I happened to have some grubs in that color with me.

 

Zoom Fat Albert Grubs in green pumpkin, rigged with a 1/0 Ozark Trails hook, and a 1/16 oz bullet weight. I felt a nibble, then some pressure...

 

 

 

Very nice bass with a huge maw!

 

I didn't have any trouble hooking up with the standard gap worm hook.

I'm starting to really like Texas rigged grubs. Seems the bass hold the same opinion.
