Thanks guys, I also love the proportions of the Skye more (4 row of hooks and 4 row of lace holes instead of a mile high 5 on the Islay), and a heel brogueing is more appealing on the Skye as well, though I like the rounded toe shape of the Islay last .. Still a bit of a mixed feelings ..
Need the boots before the ugly weather starts so I will post the photos of a purchase decision soon ..
Bear in mind the the Skye - 335 last - has a wonderful rounded toe in its own right. At least I think so....
