Default s-trac or wavetrac for Moser 9" m6 transmission

I'm running 35 spline axles so these are my two options. They're basically the same price. Which will hold better in a drag racing type driving style? I have a spool in it now but really don't care for it anymore. I run a sticky tire all the time. I know neither is as strong as a spool. Just some real life experiences with what other people have used. I think both offer a good warranty iirc.

S-Trac as I read will take more abuse.

I don't have any experience with the wavetrac but I have the strac in my s60. When I ordered it through Carl at crp he told me he has a handful of customers pushing 900 hp with the strac without any issues.

If I remember correctly Eric told me the S-trac was also lighter. I don't know how much but I'm all about saving any weight I can.

I have sold a lot of Wavetrac units, but probably more S-Trac. I have warrantied like 3 or 4 of the Wavetrac units, only one S-Trac unit and it wasn't an actual failure. The S-Trac is slightly lighter. Both are great units, made of premium alloys, carry a limited lifetime warranty. I have ran into the Wavetrac not fitting in some 9" cases.

Here ya go: MWC fabricated 9" with S-Trac diff unit and complete rear suspension, MWC full front suspension package. This is a 383 LS1, ported 243s Nitrous Outlet plate, T56 trans (HSESWS6 here)

Does the Wavetrac have much more biasing than any other diff that could/would fit into YOUR Fab 9s (with the Watts link)??
I am asking for a ROAD RACE app, NOT a drag race/launch app, and would not need that standing start strength as much as a high bias ratio (like the Torsen T2R's 4:1) to help off of corner exits/apexes.
