I would claim that different wheel setups is barely comparable to the Flow Motion Technology that Marsblade uses. Flow Motion Technology is completely stepless while for example a 72, 76, 80, 76 wheel setups is based on jumping between three steps and always balancing on maximum two wheels at the time. I think this short film visualize it in a good way:
When it comes to the feel of being locked in one direction you will notice a big difference with Flow Motion Technology. When you, for example, put the weight on the heel in a tight turn you will notice that the turning radius can be significantly reduced. However, of course, inlines have some limitation as they have another grip with the surface than a steel has with the ice.
