how often will you actually use FEL bail spear? during hay season and getting stuff off the field, and/or having bails delievered. after that 3pt hitch bail spear most likely work for moving bails from storage location, to livestock lot to feed the animals. the hassle of swapping out the general duty bucket on FEL for bail spear, once or twice a year that's not that bad of an issue. more so if you can drop bucket / bail spear on some nice concrete pad, or like. to keep everything up out of the mud / weeds.
if you have a concrete floor garage, 2x4's and 4 spinning wheels. to make a dolly to drop buck onto and/or bail spear onto. to easily push one of them around in garage for better storage / easier hooking up.
