I’m a believer in the PBR. I’ve run both ET Drags, and now PBR’s on my Satellite. The PBR was quicker in 60, and every bit as consistent. It was faster on the big end with no other changes. The car also felt more stable at speed than with the ET Drags. The only nod I would give to the bias ply tires is the look (I love the old school sidewall)

I footbrake, but I have a number of friends running 28” PBRs with a transbrake in 9.90 & 10.50 cars; both hook & book with no issues, those guys are also sold on he PBR.

Is there anything wrong with a bias ply slick on a bracket car? No. You’ll likely be just as competitive with either, but the PBR is a firmer tread compound which leads me to believe it will last longer (???... purely conjecture at this point, but I am 2 seasons in on my first set, roughly 120 passes and they still look pretty good.) I’d say they are simply a step in the direction of progress.
