I guess this is a 2 part question. I'm going to save for a seat and am curious which one is a better option. The seat concepts is way cheaper but I can't tell by the one pic on their site how durable or beefy it is. Also anyone opt for the firm foam? Anyone go all carbon? The Corbin is a beautiful seat but for $200 more I'm not convicted. Please help me. If you've got one I'd love to see pics of them installed. I've seen the threads here but want to hear it again.. Thanks.
