Ring and Pinion - What Brand ?

I've used Motive Gear in my street car and circle track car. No issues at all. Proper installation is the key with any brand. --
-- I've heard that they are a real good gear, but that's what I have. - They were new, and howled. -- They were set up 3 times, by 2 different guys (one Guy 2 times - other Guy one time) who have done, probably, 100, or more setups. - still howl at 55 - 60 MPH. -- Less than 200 total miles on the current gears. - Now i'm having them replaced, and don't know if I should switch brands. -- Thanks for the info.
