As weights are far more bigger on the Main mounts, these MLG doesn't have this problem. The brake actions of the carbon brakes fitted on nowadays aircraft are more efficient then the metal brakes which are used on the DC-10.
Not sure where you get your information, but it is mostly wrong. You are taking small bits of factual information and extrapolating from it incorrectly.
Carbon brakes wear less with autobrakes on, and the record has not indicated that there are particular problems with the CLG, as the incident history will show you. It is true the brakes were modified on the CLG, but that's where your facts end. There was never anything violent about it, and the number of failures that could possibly be attributed to the issues you describe were too small to be statistically significant. In any event, it is a non-issue now with the current brake metering.
Also, the last FCC load is 908, the FMC loads are the numbers that have been posted in earlier messages, currently up to 921.
As to your landing technique issues, never encountered those, I agree with Foxhunter.
