Power Meter vs Heart Rate Monitor

Bike Hugger has reported on an interesting study on training with a HRM or a Power Meter. The short version of that article is that the HRM came out favorably in the study beating those who trained with a Power Meter. Now there are limits to this study and Power Meters have some really nifty features but at least this keeps those of us who use heart rate monitors from feeling like we are in the stone age.
