I have put Inferno 09 diffs (all steel: spiders and all) into the MLST with a little work. It takes a bit of modding, and money ($60-$70) but so far I have run 4 3-cell packs through running a Wraith 7k and they seem to have held up fine. That's already more than I have done with the MLST2 diffs and my abusive driving style. I have almost finished my tutorial on how to put them in, I could probably get a post up here in a day or so.
