I tried to talk some people out of buying the Power when they say they have a more upright riding position, but others have said it works for them even when not racing. I suppose the flatter profile is more pleasing to some tushes.
OP: some things you can do for free before spending money on a new saddle is to make sure you are giving your butt periodic breaks. Stand up and pedal for 10-60 seconds every 10-20 minutes. Get off the bike and stretch or walk around. Your sit bones may grow accustomed to the load after a few rides also. It's normal to feel a bit of pain when you first start riding longer. If you're already doing those things, then a new saddle may be just the ticket to comfort.
