You are right about the H&R being more streetable. But by the time you can really utilize the Wolfe bar, your car has already lost a lot of its street manners. I know what everybody is going to say, " I drive my 10 second GN 5,000 miles to church and pick up groceries with my Mother every Sunday, yada, yada, yada." Believe me when mine is not broken I drive the hell out of it. That's why it has a pair of child seats in the back seat. 
But if it is NHRA legal it has the minimum of a roll bar, if not a cage. You have to climb over a bar to get in to both front seats, unless you have swingouts. And you have already lost the back seat because of the crossbar on the main hoop unless you are a 5 year old that thinks it is a jungle gym. More than likely a 10 second Regal has at least front drag shocks, sway bar removed, and skinnys. So even though they are drivable, a lot has been already been sacrificed to go fast. But to each their own. The H&R bar is nice, no doubt about that. But if I was to spend the money for a new bar, it would be a Wolfe. Used on the other hand. I have friends that run the Wolfe style on their Mustangs with no problems.

even when new, creating some rattle, but since I did that, I never had to touch it again!
