I think it's absolutely stunning. What holds me back is the steep premium over the very nearly as nice standard wholecut.
Been a little while since I bought my chukkas, which was the last time I checked them out, so I'm not solid on the exact numbers. But I recall something in the neighborhood of an $800 premium - and remember thinking what a nice second pair of shoes that would buy.
Of course, with sufficiently deep pockets, such considerations are irrelevant. And I absolutely get the appeal of the seamless in terms of aesthetics, exclusivity and craftsmanship. They are simply terrific.
