Trans brake reactions

Two years ago we went from a TF727 with a Turbo Action trans brake to a Keith Long built TF904 with a Griner brake. We did this because it's easier to remove and replace the 904 compared to the 727. We also needed to pick up some ET. The swap accomplished both of those things.
We got another benefit that we didn't plan on. After the transmission swap I had to add .095 of a second to the delay box. I'm not going to install a Power Glide in my car, but what is your experience with going from a TF to a Power Glide as far as your reaction goes? If you have done it.
We're going to be doing a lot of index racing going forward. We have plenty of areas to address the cars reacting. Just wondering what other racers have experienced.
