Great review IMO. Totally agree on durability -- front arms break when you hit things you should not have hit. Funny thing is I ran the stock ball cups for 2 months with only one break and they only popped off when an arm would break. Put RPM's on and first day out a steering ball cup popped off in a small alteration with a SCT. So your mileage may vary ... my guess is that some batches of ball cups work, others clearly do not.

Zero issues for me popping dog bones with the stock setup.
