Ill chime in with the opposing viewpoint .. a square taper cold forged aluminum crank is fine
for chainline, the left side is not significant
right side fixed cup face to spindle end .. match that.
.
Shimano's UN types work well... (and low cost)
@ $150. , probably not willing to spend up for
SKF
IRD is about half that ..
Phil Wood is USA Made . they are very fine tunable .. in chainline ..
....
