I have only used the advanced set up (smaller in front) so I don’t know the difference. I do like the way my stride feels thru the toe of my skate with the set up, but could feel the same with all wheels the same size. Both of my sons play competitive roller, though not lately, in their O1s. My youngest (13) likes the smaller wheel in front but my oldest who is 6’3” and 200+ likes all the wheels to be the same size. He feels more stability on turns with all 4 wheels the same size and making contact with the surface.
