The real advantage as I said above, is that shafts are lower maintenance, bullet proof and cheap.
Shafts lose ground when torque steering becomes a problem, but that is only if you run mod, boosted or low wind stock. We have shaft cars in stock (13.5 blinky) which show absolutely no problems.
You can decide for yourself if you want to continue your discussion with Bert, but you should know he brags about he is going to run 2.5t BL motors with his cars and he wonders why the pros don't follow his "thinking". Be warned, I had the misfortune of reading hundreds of posts of his that help no one.
