I'm curious about upgrading my seat since I do ride alot in the hills and street. I was wanting to here what you guys have to say about "Saddlemen" seats or "Corbin". I want more comfort. And which one is more bulky? or can you even tell? So lets hear what you guys have to say. I'm going to get a seat soon, but I'd like as much info as possible since I've never ridden with either one. Thanks!
