We installed a Hurst shifter on my uncle's '11 GT. I have power shifted 2nd, 3rd, 4th and 5th at 6,800 RPM's numerous times and it is a very slick shifter.
I like it better than the Barton that is in my '11 GT and the Steeda that is in my '11 V6.
I'm hoping to find a used one at a good price and put it in my GT and sell my Barton.
