+1 on ditching the suspension seat. I have one on my hybrid (Specialized Crossroads), as well as a fork suspension, and I'm pretty sure that I don't need them. When I bought my bike a few years ago, it seemed like a good idea, but I didn't really know what I was doing. I'm primarily riding on local streets, and occasionally on a dirt path. I feel like I'm losing more of my energy in the suspension when I'm really pumping the pedals than I'm gaining in comfort other times.
