Just wondering why you had to toss a cone style, I have had real good luck with them for the past 30 years, sometimes shimming and machining is needed, but not often.
I have run clutch styles also with minor issues.
Most of the time excessive wear is caused by the wrong fluid or additives which causes the cones/clutches to slip and basically overheat, wear and abuse does take it toll but any rear will eventually get tired.
