That is a very cool setup. Very practical.
Me I'm a fan of tall sissy bars. Had an 18" from BDM, sold it and got a 25" from Ginz which as some know, cracked on me on my way to BB&BBQ -- awaiting new one from Ginz as we speak.
As for Ginz as a company, I can't say enough positive things about them. I bought my 25" Catherdral bar with custom luggage rack welded on in 2016 -- they are covering the damage I just sustained 3yrs later. My hats off to Gary (Gin) this is truly customer support.
