I think the key here is body weight. At 155, stock seat works fine for me.
You are most likely correct on that - but I'm 165 lbs at 5'11" so that's not really the case here. I've been thinking about replacing the seat since I bought this bike actually. The longer I'm in the saddle the worse things become. All day and multi-day rides are becoming a bit much and planning on more multi-day excursions.
All good feedback from everyone - much appreciated.
I've had Mustang and Lepera and they were great. Having Allen at Mean City Cycles redo my stock seat for my weight and doing the tailbone relief mod has turned out to be the most comfortable for me out of all of them.
