The user digital_denim posted a couple of pictures comparing the fit between the Fullcount 1108(66 model, high rise, slim, straight legs) and the Studio D'Artisan SD-103's on superfuture.
Apparently the fit is quite similar, as is the leg opening, but keep in mind that the 1108's pictured have not been shrunk yet, so they should end up a bit slimmer than the 103's.
Because of the higher rise on the 1108's, you should go down 1 or 2 sizes, unless you have beer belly. digital_denim went down 2 sizes, which was a good call in my opinion!
