I agree that a 4 eyelet would work better, and as long as the shoe creases properly, I'll be fine. I have the Neumora, and get some double creasing due to the elongated 333 last.
UPDATE: Interestingly enough, where most balmorals are lasted with the eyestay touching (if you've ever seen a pair being made, they use a plastic tie to keep the eyestays together while lasting), it seems that the Hanover is lasted with a natural "V".
Interesting on the lasting! But as long as the shoes are comfortable, that's all that matters.
I emailed jville a while ago to ask what last the Saunders were on, and got the following reply: "it is close to our Regent Street, kind of snug in the heel but room in the toe box." Regent appears to be discontinued, but a little searching shows it was on the 4-234 last. Hope that helps. FWIW, I have a pair of Saunders in tan, and love them!!
I'm going to go ahead and disagree with AE in their description. I don't own any shoes on the 4-last, but I advise buying Saunders in a wider width if you normally are a medium width. I don't find the heel any narrower, but the toe box is tight and elongated.
