The group I ride with at the local club tends to mix it. Regular mountain biking seems to have done great things for power level on the road. I forgot to shift on a hill that when I first started riding I needed to be in the small chainring and now usually do in the middle. It was cool to be able to power up that sucker in my big ring. I won't do it that way all the time - don't want to encourage knee problems.
