My next recomendation would be to save an extra $75 and buy some Hope Minis. they sell for $150 per wheel from most shops. They have more power then you will need, great modulation and have a nice finish to them. They are a XC system but i have used my wife's bike on some dh runs and they worked great ( I weigh 270lbs) with out fading. If you can wait until Monday night I can let you know about the Hayes.
