The other point on saddle position is that it's not exclusively to do with weight above pedals (powerful downstroke) vs. weight behind pedals (smoth circles) there's also the issue of hip angle - you need to be pretty open to get power. this is more of an issue for lo-pro's and road bikes with tri-bars - or when the handlebar reach is too long for you.
