Corbins are VERY firm by design. Maybe not for everyone. I currently have one on my 73 850 and love it. I have done a couple of 400+ mile days and one close to 700 miler. Seat worked well. I had one on my previous HD Roadking for 100,000 miles and loved it. Too many long days on that saddle to count. 100K, obviously worked well for me. My wife used an Airhawk on the passenger seat since she found that the Corbin was a little too low for her back to interface properly with the tour-pac padded back rest. We put a Corbin on our new 2016 Roadking and the passenger height has been increased. No Airhawk as it works well for her and the tour-pac. Crap, here I go rambling again. Buy what YOU like since it's your dollars that are being spent.
