t56 main shaft question I was looking at the different transmission sponsors here and I see that Texas Drivetrain Performance are the only ones that offer a 31 spline as a upgrade over the viper shaft. Is this a worthwhile upgrade? Why are no other shops doing the 31 spline main shaft?

IMO, its half dozen in one hand and 6 in the other. I use the Viper shaft because its what I've always used and stocked. As I have said in the past, I personally do not believe there is any real measurable difference between the two. One uses a Ford yoke and the other uses a Dodge yoke.
But you know what they say about opinions so take it for what its worth I suppose.

FWIW, I also updated the 32-spline write-up with new tremec p/n's that drop the 3pc syncro lock down from GM's $200, to $30..

To the OP, I think the reason that no one else uses the 31-sp shaft is that it's not a direct fit, as it has to be machined in order to work in the f-body trans. The Viper shaft is a direct "bolt in"....just has to be shortened by 1 3/8in.
Yes, that's true. I got some bad news yesterday, though. The 31-sp shaft that I've been using very well may be discontinued 
Just a rumor, so we'll see.
The good news is that I ran across another machine shop that can produce any shaft from scratch
Maybe... 32-splines for all! Just not sure on the pricing yet, as it may be much more expensive.

Same reason we use them, I can promise you guys, you will rip the teeth off the input and cluster gear before breaking the 30 spline Viper shaft. Anything stronger is really just for bragging rights I guess.

And just to be clear, the 32-spline upgrade is about a stronger triple/double cone synchro upgraded T56, not bragging rights. The 30/31-spline shafts work with the older double/single synchros that came in the F-body. The only triple/double 30-spline I'm aware of is the $600 aftermarket 9310 mainshaft.
