Namor pretty much said it. If you are a prima donna and expect to get the exact-fucking-thing-that-came-from-the-factory you will be disappointed. If you understand it is the best non-manufacterer resole you will be very happy. FWIW, a lot of people on here aren't even getting channeled stitching, which I think they do very well and create a nice beveled waist. Honestly, from eye to shoe distance regardless of what method you use to resole not you, or anybody will be able to tell the difference. Most of the manufacturers as I said before create a real hassle for the customer to get a resole, the cost is high, the time is long, and I personally can't be bothered.
As for neoprene, I personally haven't worn it, I think crepes just look downright ugly. I love the look and feel of a leather sole. Dianites while thin there is something about seeing the bottom of a dress shoe in rubber that bothers me. Something nice about seeing somebody walking and the underside of the shoes are natural. Call me crazy, but it is what it is. Also, like I said before oak bark soles get a nap on them almost like suede when you wear them so they do grip much better than regular tanned soles that get slick and slippery.
