For me, the suede makes it look less like a hard-wearing winter boot and more a little more upscale. I think it allows me to wear it to the office and throughout the work day without looking so much like I'm wearing a winter boot.
Both mocha and mink suede look nice. I can't discern the difference enough to have a strong preference. I'm ok with the 64 last but will need some advice as to the proper size. For EG, the 888 last fits me perfectly in a 7/7.5 D. Perhaps skoatiebaloget can give me some advice.
Badsha - On jodek's website, search under Drapers rather than cacioppolli. I bet it is the one listed as fabric number 8356 - green donegal from the salt & pepper/covercoat book in 10.5 ounces because mine is 8352.
I don't have the exact number but it is from the cacioppolli book called "salt and pepper and covercoat". Try to get a large swatch if you can and be careful - that particular fabric can really wash out certain skin tones. I went with the more traditional gray from the same book.
