Bias ply slicks vs drag radials

Some different things to consider here and I appreciate everyone's thoughts. I was hoping for some different opinions and experiences would weigh in and I wasn't disappointed. I hope to be going to Cecil County this weekend and I will see what they are using down there.
Thanks,
Bill
I have friends that race at Cecil and they brag on the incredible prep there so I can guarantee you that most will be on a radial as they are absolute fastest tire on the track.
