OS better step it up. even the speed, guys are putting ninja parts in them, that has to tell ya somthin!!
Interesting comments it depend on the user and how he/she maintain and runs the mills doesn't matter what TOP brand nothing is bullet proof but OS for sure is very easy to tune. I only run OS speeds and JX21 never had any issues they are solid cannot comment on vspecs but were I race 90 percent of all mills are OS badged.
