Unfortunately, I'm too tall to ride this comfortably. Naturally, knowing the layout helps very much. However, every time I ride, there are about two elements that make it feel like someone is rapidly Karate chopping my lower neck.
In response to Zimmy, I completely understand your sentiments about B&M harnesses. If I was maybe two inches shorter, the head banging would get my entire head. Instead, for me, it balances the forces between my head and neck, to the point where I can more easily avoid any issues.
There is a German phrase that goes "Jede Tierchen sein Plaäsirchen." [Yay•der tier(here)•chen sein(mine) plus•ear•chen].
That means "Every creature has their own pleasures."
