Jerry when still using a MLS and the SS o rings is the process any different then with a composite setup, like do the rings themself need to be deeper in the groove so it doesnt crush the MLS. also why does everyone seem to run a mitsu mls with o-rings but its forbiddin to run a cometic mls with o-rings, or atleast no one recomends it? whats the difference between those 2 MLS?
