old style locking hubs

[Vintage Windmills]

Im not convinced anything is better than the spicers yet. Has there ever been a spicer thats failed due to something other than someone putting pliers on the knob? Just because the selectos don,t use plastic doesnt automatically mean they.re better quality. Maybe they are, i havent reaearched them or have experience with them. Was the machining and metal hardness or contact area as good or better than the spicers? Since the strength of steel can vary from 36 ksi to 180ksi depending on alloy and heat treatment, im looking for more than just an appearance difference. If there are reports of spicers stripping out and selectros or others not, Im all ears.
