Andrew,
as you know, it it just the opposite here, we mostly use full axles. Price is about the same and installation is a bit easier. My indecision about hub face dimension sent me to the half axles. I am regretting it a bit because where I would like to put the unit has the outboard screws into the frame rail. I would not have this problem with a full due the way they are mounted. No problem, I have a work-around if need be. The planning is more than half the fun in most endeavors.
