WHY would you want to run ONE rear for all three competitions???

Lightweight but strong is best for the drag race and it will need shock mounts and some suspension. That rear can also be used on the dyno provided it is stuffed with gears that work well to load your combination without overspeeding your tires. Otherwise you may want to swap to a dyno rear axle if it is easier than changing gears in the pits...

Then for the pull you want something super strong and heavy with solid suspension and likely different gear ratios yet again for proper tire and pull speed down the track in your powerband. Again, probably better to have an option that will bolt in to give you what you need rather than twisting up something that "might" work!

My 2 cents...
