I use ISO on backhoes, and I'm more proficient with this pattern than SAE. Now today I got on a mini excavator for the first time, and it was on ISO pattern and the controls felt awkward, was it because of the joy sticks being different from the two levers from a backhoe that threw me off? I've been operating a cat 320L recently on SAE controls that I'm pretty comfortable with could it be that I prefer SAE on an excavator than ISO? Please this is really bothering me.
