From your photos I can't tell which one is the U Last which is a good thing as I thought only U and F has that 'Sleek last. Would be great to compare the toe shape of your Vass. I'm hoping I won't like them to save some $$$ that aside, which last has the narrowest heel and lowest instep? My U Last fits perfect but the midfoot width is a bit loose that is probably why I have this creasing.They had a sale late April. I got a half-size down for the R but kind of regret it. It would have been fine at my usual U and K size. Will shoot some more pics. What exactly are you looking for?
