Caltracs shock options?

Hello everyone, I am waiting for my HDK k-member setup to show up and I was wondering what shocks everyone is running on their 1/4 mile cars? I was thinking about going with Afco double adjustable but looking for others experience before I buy the shocks. I've been reading other threads but most are older so I wanted to see if anything has changed that I might have missed. Thanks for any info. Car is a 73 Challenger with a 572 Hemi 750hp/727 TF with a mini tub job and 3.7 gears.
