You may still break stuff with a solid, but not nearly at the same rate as an IRS. I've had stock shafts, Level 5's and a solid and the solid is the best choice for the frequent drag racer. If you don't drag race alot (or don't mind fixing broken parts), the IRS has tons of advantages.
We probably wouldn't break so much stuff if these cars weren't so heavy.
