After quite an adventure of mishaps on Saturday, I've determined I need to assemble an emergency kit. The first step, as I see it, is something in which to store everything. There seem to be a lot of options in terms of top cases - BMW aluminum, Vario, GIVI, etc. What's the prevailing opinion on the best bang for my buck? I'd like to be able to fit my helmet in there as well, if that changes your answer. Appreciate any guidance that can be offered!
