Looks like you are on the right track. For hours of comfort you will need to let go of soft wide saddles. Just wide enough to fit, and minimal to no padding. Then you have to remember to do the thing where you get out of the saddle for a minute or so at a time to let the blood flow back, to allow your rear to condition up. Every 15 minutes or so at first. Really helps a lot, after a few long rides doing this you can really tell you are dialing in. One of the best tips I got from this entire forum.
