How do I choose between Detroit Locker and Powertrax?

[NOSstang89]

Both manufacturers make several different models of differentials, and I'm having trouble choosing which to go with. My car is becoming less of a street car every time I put something else on it, but I still drive it on the street regularly. My main concern is building a rear end that won't break from 5000+ rpm launches on slicks. I plan to get at least 31 spline forged axles (I would really prefer 33 or 35), C clip eliminators, and a diff. cover girdle. How do these differentials behave on the street and at the track? Thanks!!
