Wheeler's Superbumps vs Durobumps

I've been wanting to get the Wheelers Superbumps, but came across the Durobumps. I have read nothing but good things about the Superbumps and people really like them. Also, have read nothing but good things about the Durobumps. Just wondering if anyone knows the difference between the two?

 

Superbumps are dense foam based and
Durobumps are stronger rubber compound.
Don’t know much else. I’m running durobumps

 

I have ran both. Duros are less bouncy during daily driving.

 

I have only ever run Durobumps. But I will say Curtis from toyotabumpstops offers exceptional customer service. I don't have any experience with wheelers, but for the customer service alone I don't think I'll ever use anything but Durobumps.

 

Which rear durobumps should I get. Short or long? I have Deaver J66 and fox 2.5s in rear
