Ok, so I am looking into the differential replacement upgrade to a ball differential and Ive read some things about different brands. Is the 3 racing ball diff not so good?? Which is the best and TOUGHEST diff that wont break and consistently put out good performance??? I'm looking at Tamiya's diff but is it that much different and worth the extra coins? Anyone have experience with more than one brand of these ball diffs and the best way to assemble? First time replacing a diff so any help would be good on why other brands are worse than Tamiya. Just trying to get as much intel I can to make a good purchase.

And for the update on the spur gear I destroyed today....NO SPARE lol.... so we are decomissioned until further repairs (will be getting the black reinforced gears to sakadachi) lol stupid curb
