nope. you want 8cdr on ring for sure. even with leorics crown. most saders make the mistake of thinking you only need 56cdr for perma akkhan. thats the MINIMUM you need not the MAXIMUM. you want MAX cdr if possible without losing too many other stats. rings (both), helm, gloves, shoulders, shield, weapon should all have max cdr. ammy shouldnt have cdr unless you have a godlike flavor of time. belt is the only place id drop cdr.
You need 55.6% CDR for permanent AC. Maybe you want a teensy bit more to cover for human error in re-applying AC. After that all extra CDR is pretty much wasted in lieu of more damaging stats (i.e. you don't want CDR on your neck piece because you're giving up 1000 Str 100% CHD or 10% CHC, whereas you only lose 6% or 50% CHD if you take CDR on ring).
Going for MAX CDR is just overkill.
