^^I don't like suspension posts - they make me feel less connected to the bike. However maybe I just haven't ridden on a good one. Invisibl - I'm not sure what the problem is...is it that your butt or wrists are jolted by the road, or something else? If it's road jolts, remember when you go over rough patches you should stand or at least tense your legs to absorb some of the shock.
Re the comfort seat: echoing what MichaelW said, it's been claimed that really cushiony seats are a threat to your masculinity - you sink into them and they choke off the blood supply to the vital nerves and organs, and you get numb down there, which might lead to sexual dysfunction. According to this theory, a firmer seat allows your sit bones (ischial tuberosities) to carry more of your weight. It may be more uncomfortable at first, until you get used to it, but better for you in the long run.
