Was going to suggest these, but they're out. I managed to grab a sample pair of them, but the reviews are right, they are very wide-legged. Definitely going to have to get them slimmed up in the leg and reduce the fork on them, as the crotch drop was pretty severe. Nice trousers though.
Only other suggestion would be RRL or just having them custom made.
