My 13" shield is mounted and I love it. The 15" was just a bit tall for me, but the 13" is just right for the way I sit/my height. Mark had me drill extra holes in the messed up one that was sent too, so i ended up with two shields. Not that the taller one will see much use, but it was nice.

The Madstad makes for a nicer riding experience than my old fixed shield. Small tilts and adjustments make a difference. Love it.
