Not I, but good luck in the search. I love my Givi E55NT Maxia case and so does the wife.
LJCorby, how did you mount yours and did you use the backrest?
We went for a short ride wth the trunk on, and the SO was not happy.
The trunk was bouncing and hitting her in the back.
The backrest seems to push her too far forward so I didn't mount it.
