Im with Mistercrash... composite CVD's are the way to go. I never liked the idea of bending a metal CVD and having to replace it ($$$)... or have it vibrate the car with an 8 turn in it (ruined bearings), so i went with the composites and have loved them ever since. Doesnt matter what diff i use them with. I think i have broke maybe two in all the years i have had this car... and both were from impacts (one was head-on) with other cars in traffic, never from one-way use. I just add the IRS pincushions to the stock AE composite bone to protect the outdrive and go with it. I have noted on high bite carpet or asphalt with modified, the response can be inconsistent when stabbing the throttle... most likely because the composite bone twists under the load. Smoothing out the power transfer (trigger finger) or going higher on the speedo frequency seems to help that alot. Dunno... just thought i would add my .02...
