I have the Corbin & Back Rest. Never road it with the stock seat so can't compare. I can do a 250 mile day-ride and be a little saddle sore (no real endurance anymore). But what I notice is that I can climb on again the next day and have no residule soreness. THAT would be nice on a trip. I love the back rest...first one I've had. All in all I feel the Corbin and Back Rest is a great combination. Yes it's purdy darn firm but hey...it feel good mile after mile!!
