My info as it stands is if you want you can go below the path ie drop down contour etc but you can't cross the plateau. so stick too path. To cp below Winn Hill, I know of no restrictions, either follow the obvious path or take your best reccied line..
Kit I'd bring every thing just in case. it will still be full water proofs map and compass etc. the extras may or may not be eased, bear in mind that over recent years we have had many serious incidents of Hypothermia so the RO may err on the side of caution
I'll be at Mam nick I think and then at the end selling ale.
