Wow Airkoneck, that is some experience! So nice to hear they were so accommodating. How much will that seat cost you in the end? Is it an air seat? Are you thinking you're gonna keep it?
Truthfully, the shape seems exactly the identical to my Corbin dual tour seat. I mean your seat has much nicer stitching in the saddle, and there appears to be a backrest slot behind the driver's saddle, mine has it for the passenger, which is what I needed for my wife, but otherwise the seats look quite similar...

I know Corbin's are a litte overly expensive, but once broken in, mine is amzingly comfortable, and did move me slightly closer, as yours seems to...
So how about a review bro?
Your'e right, it does appear to be like the Corbin you have there (nice seat btw). It is listed at around $850 on the Danny Gray site, but from what I can see, dealers list them anywhere from $50-100 below MSRP. Sherry at DG said she would contact one of their close dealers when I am ready to buy and tell them to give me a deal (DG can't discount their own products due to contracts with their dealers).
As far as reviewing the seat, I only rode on it about 100 miles so far. It is an air seat which has a couple of neat things about it: 1) once you figure out the right amount of air to satisfy your own rear end, it feels really nice and does a good job of distributing your weight and minimizing pressure points. 2) Mid ride, you can deflate the seat a little bit just to change things up which is almost like stopping the bike for a moment and stretching. Well not exactly but it gives you butt a different feel to the seat which is refreshing.
The seat does seem to feel slightly cooler than the stock as well although it was not overly warm outside today. It just seemed like I had a cool seat to sit on the whole time but I will see more down the line.
As of right now I am leaning towards keeping it. I'm going to do a 400+ mile ride to Whitney Portal on Tuesday with my fiance so we can both make a final judgement on it and decide then. I'll keep you posted on how the seat does on a longer (and probably warmer) ride.
