how many run a driveshaft loop

I got one in the Duster. The strip I go to says if you run slicks, you have
to run a loop. I busted a front joint at the starting line 2 years ago. Glad
I had it. I run drag radials. I did my burn out, no problems. Got up to the
line. Pre loaded the suspension, let the brake go and it broke right away.
