Since I got my Voyager in April 2016, I have put about 22000 miles on it with stock seats. My longest mileage day was 986 and my normal average when traveling is 500-650 miles per day. (I take long trips)
After the first 12,000 butt numbing miles, I figured out that if I combined an Alaska Leather gel pad and Air Hawk, I could do my long riding days in relative comfort. I just didn't care for the solution. What it taught me was that for me to be comfortable, I needed a bit more height in the seat and some more support.
I stopped at Carl Leo's house in July while on my way for a 2000 mile trip up to Front Royal, VA to ride Skyline Drive and the entire Blue Ridge to pick up a part and he showed me his new seat. I sat on it and it felt very promising. So I finally decided to just get my stock seats reworked to my specifications and am now in process of testing it out.
The seats were done by Terry's Custom Seats. https://www.terryscustomseats.com/
The price in my opinion is very reasonable starting at $250 per bucket. I was originally going to only have my driver seat done to save money, but my wife said she would like a more comfortable seat for those rare occasions when she rides with me
Since I wanted mine raised up, there was an reasonable extra charge for it. So, here are the pictures of both seats on the bike. 
My first 120 mile solo ride seems promising. Still getting used to the new height, width and extra support. Previously, I had to sit all the way back in the seat where the foam was so thin my tailbone pretty much was riding on the seat tray (which is why I had to use 2 pads to help.
I plan to do more test rides and maybe a longer riding day to see if I can now retire the Air Hawk.
I left the Markland backrest off for now. Having it on seems to hold me a bit more forward than I like. I may have to either modify it or sell it and get a Utopia backrest or just do like I did before the Markland and use my duffle bag on the seat.
If interested, feel free to check out Terry's website and send him an email for more information. If you have other questions for me I will do my best to answer.
One thing to note, because I had my driver seat raised about 1.5 inches, I had to get a little creative with the rear seat since I would not be able to slide the rear seat forward over the driver seat. I ended up putting some short studs in the rear seat mounting holes and got nut to secure the seat. I also locked the seat adjuster in the rear most position. I can now get the rear seat off pretty easily, but I need a 10mm wrench instead of a socket. I put the front holders in place and lower the seat mount holes over the studs and then using two fingers get the nut started. Then a few turns with the 10mm wrench and all is well. I will be experimenting with raising the rear seat a bit as well to retain the adjustment feature. If you don't have your driver seat raised, it should not be an issue if you choose getting your seat done.
Thanks
