This is just idle musing but I wonder would the DS3000's actually be more likely to cause fade in your case?
e.g. they will certianly brake harder for a while, but presumably this will heat the disk up more which is likely your weak link in being able to shed the heat.
You might need Castrol SRF to avoid boiling even normal 300 BP upgraded fluid?
I don't know that all of the above defintely follows, but I don't know that it doesn't either
