Roger, Haven't seen the rolling butt leather yet. Any of my customers with this concert instrument prefer to use it for gentle musical applications like photo storage and perhaps Alfred's Intro to the pieana. Clever how the folks designed the slapper/thumper rail to provide two options: percussion on downbeat or on the offbeat (key release) by merely a slight moving of the rail closer to the key buttons. I did mean to say in the previous post 'loose letoff rail hangers' as I saw in a grey Yamaha U1. It was late for an old guy. (OT: Saw your C7 keys at my friend Bruce's place) Ralph Thorn
