by the way some of you speak in threads it throws me off, from what I've always referred to a T-rig...

I've always been under the impression a texas rigged plastic, is a plastic that is rigged weedless with a bullet weight on top of the plastic. I thought those features combined together created the "Texas rig"

so I don't understand when people say weightless t-rig, How can it be a t-rig without a bullet weight on it? what about that makes it a t-rig then, the weedless hook? please explain in great detail.

If that is the case the why wouldn't you call a worm that is rigged weedless with the hook pushed in on the plastic on a c-rig be considered a t-rig? because of the weight placement and type right?

I thought a c-rig was weight up on the line...

and t-rig was weight on right top of the plastic

i'm sure you'll have to read all that twice to understand what i'm asking, sorry... i'm just confused

I think you've got it figured out.  A weightless t-rig is rigged with a weedless hook but no weight.  You may rig a worm on a c-rig in the same weedless manner, but it is a c-rig because of the placement of the weight, bead, and swivel, and the use of a leader.  Some of us fish something like a c-rig but with a split shot attached where the c-rig weight and leader would be.  This is called a split shot rig.

I've gone on about my different way of the C-rig before... I simply just make my T-rig into a C-rig by moving the bullet weight up where I want it and then Peg it, sure it's not the Traditional way of C-rigging but it's quick and proven effective.  8-) GOOD LUCK

I don't know if anyone actually, officially defined a weightless t-rig.  I was unable to find this in my dictionary.    When weightless plastics became all the rage, the term, weightless t-rig, came into use and everyone accepted it as a t-rig without the weight.  Whether it is semantically correct or not with regard to the original meaning of t-rig, I don't know.  I just assume that terminology changes with time.   It is an interesting question, though, and it is one that I have wondered about myself.  

T-rig: Texas-rig

The "traditional" rig includes the weight, but as senile1 pointed out, common usage has changed over time. The designation is the same whether the weight is pegged or allowed to move freely (unpegged). A bead may also be used between the weight and the hook.

C-rig: Carolina rig

This includes a weight, bead, swivel and leader.

A split shot rig is simply a weight fixed in place an arbitrary distance above the hook.
