Hi there - I just ordered the current 'small' GS tank bag for my GSA. (Only one 'large' size listed for the GSA but it looks like it should fit the tank shape ok? Anyone done the same? I think it was about £117 versus around £170? The large one looks too tall for an already tall tank. Also, what is a good way to protect the tank? Any good clear film out there? Have seen a factory 3 pad thing on some GSs and GSAs but I previously had some thick, clear film on my old GS.......just can't remember where I got it! Many thanks. LBJ.
