What's instant, most noticable difference on performance L4 diff and L3 diff? I'm consider to upgrade my L3 with L4 diff since L3 one doesn't feel smooth enough (compare with my other EP diff), but is that going to give lots performance advantage?
btw, I run lots loss diff on 1/12 than any of my 1/10 EP TC. Is that correct? Or I just use diff to correct my setting mistake elseplace?
