Which Driveshaft is better (1LE or 4thGen)?

Goal for my car is 11s...
Having said that, which is better for my car (without taking cost into consideration)...

1LE aluminum?
4th gen aluminum?
some other type?

Also, isn't the 4th gen stronger than the 1LE due to its greater diameter (2.75" vs 3")?

Thanks

Aluminum isn't really recommended for drag racing. Although it's light, it actually flexes too much for a high HP car. Factory driveshafts just don't cut it anyway in high HP cars.

Best driveshaft? If you have the money get a carbon fiber driveshaft.
