Thanks for the input. I think I am going to stick with the combo bulks. In my experience the aluminum diff case really made the stock diffs alot more durable and that was really the primary reason for going with the aluminum combo bulks.

I was thinking that the plastic drive shafts woukd be strong enough since way back when I did a revo conversion the plastic shafts actually held up better than most of the steel CVDs I tried going to the wheels. Over time they did start to stretch and twist at the joints, but was also running a 6s setup. When they started to get loose I just replaced them. But back then I did have steel dog bones in the center. The plastic center shafts was what I was mostly wondering about.
