NutHatch, I have one and the cut out is absolutely unnoticeable (though the longest rides has only been 24 miles). There are a couple of people over on the bikejournal forum that swear by the saddle, one calling it her Magic Red Saddle. Mimi's husband, Raleighdon, is another who just rode a 200k on it.
You can find out lots more info here. The saddle needs no break in (though you'll adjust the leather tnesion over time) and has 10 cm rails providing much more fore/aft adjustability in addition to its longer length, which is much longer than the most common Brooks that I see and I, too, like long saddles. When you read the measurements, note that the width is really the distance from the idents put in the top of the saddle for your sit bones.
BTW, Pam, the company is out of Fairfield, CA. The saddles are just made in Wisconsin.
