I've seen numerous references now across the web to the Fellsman having one of the toughest kit checks in the country. So what does this mean in practice? I've never failed a kit check in my life despite sometimes (MM's) cutting kit to a minimum, so is there a reason for me to start worrying now?

I appreciate lists can be open to interpretation at times, but are the Fellsman organisers particularly harsh with their interpretation? For example a survival bag could be a foil bag, or a bivvy bag, or a bothy bag. Should I be worried if I only have the foil bag version despite it being BMC rated? What issues/discussions have people had with the kit checkers over the years?

I know i'll be packing something to (in my view) address each requirement on the list, plus additional items in reality. But if my judgement is off then there won't be time to source alternatives, though i'll be taking plenty of options with me to judge against the last minute forecast.
