I have always run a Torqueflite, but it wasn't easy making it consistent. If your goal is winning bracket races, and that is more important, go glide if you want to. It really is helpful in consistency due to one shift, and that one being down track far enough that it is easier to hit the exact rpm. The 727 takes more power to turn, so there is some trade off there, and that combined with too much starting line ratio for fast cars is probably why some say the glide is faster, some say it is slower. It really depends on the power curve, weight, tires, etc. If a car has 1000 hp and weighs 2500 lbs, it would be a real bear to get it off the line cleanly with a Torqueflite with a 2.45 low gear.
I don't worry about what others think about what i do; none of them write the checks, I do. And I bet, so do you.
