In reply to omerta:
Paramo do different leg lengths on at least some of their women's kit. Although, again, the fit can be a bit strange!
George Fisher in Keswick had a small section of women's trousers in long leg length, because I ended up in that section by mistake - if you phoned them up, they'd probably tell you what they stocked. I think it was a TNF pair I was looking at, but there were maybe two or three brands. Needlesports stock some too, I think.
