ah, didnt notice that. Still....you wont break a HB pro diff, I did my testing with the NON hardend version and never broke a properly shimmed gear. I broke wheels, but never hurt the diffs. Dont get sucked into the hype.
Indeed, this is all relevent to me too. I will see how the 3.3 diffs hold up with the hvmaxx, but if they implode I may be getting something a bit more sturdy- we will see when the time comes....
