No worries, Mate, it's an oft-neglected area. But, when you think about it for a moment or two, it really is quite important. Whichever trolley JoLee goes for (or gets given), she will be stuck with it (day in, day out) for what, ten years or more? So why (should she) settle for "minimum"? Like everything else (toolkits come to mind), it's best to sit down and think about it, and then get it right
from the start.
