Just a cold Common Snipe?

Mantle pattern similar to Jack Snipe

 This bird is currently at Conwy RSPB, I was wondering what others thought? It stood out amongst the surrounding Common Snipe as looking much colder, slightly shorter-billed and having a different looking face. It seems to show dark-barred axillaries which is a good feature of Wilson's Snipe. Unfortunately, I haven't managed any pictures of the under-wings or tail yet but it looks interesting. It is a difficult species because Snipe are so variable and many features overlap with those of Wilson's Snipe.  It was outside the Tal-y-fan hide yesterday morning then on the first island opposite the far viewing screen this morning if anyone is interested in seeing it.
