A bit of background first. Ride a VFR to work daily, new job requires me to carry a 15 inch laptop, plus various files. Options I have considered are backpack - unfortunately my neck is stuffed and I can't ride with a backpack with anything more than my lunch in it Tankbag - not sure about these, never used one. My preference is for a hard bag, and I'm not sure I want to trust a magnetic one with my boss's $6k laptop in it Top box - I think this is my preference. Looked at genuine - phar-out! Almost $1k. There is also R-Jays and Givi? Has anyone had any experience with either of these brands, and can make a recommendation as to which one?? I have a sturdy rack on the back so I'm hoping just to connect the base plate for the top box straight to it. Happy to be talked into something else (but not a freakin car!).
