|ISI carrier on our 80 series and the bikes survived 12 months doing a lap around Australia. Even though the bikes were constantly covered in dust, neither frame had a mark left on it. And not even the Telegraph track could bust the carrier when it dragged through the deep ruts.
We've now downsized our 4WD activities, but we still like to head off road now and again, hence the Grand Vitara (mini 4WD). I'll mainly be carrying the road bike, but I will also do the occasional MTB enduro and need to carry the Norco.
I'm set on the ISI too (not interested in cheaper or lesser quality alternatives)
