Can't comment on the HS-1 rotor, but I had 160s front and rear on the Specialized FSR XC with BB5's and currently have 160s on the 05 Rockhopper with BB7s and they perform perfectly. Unless you're doing downhills I don't see the need to go with the bigger rotor. If I remember correctly, you're currently using Avid V's. You'll enjoy the BB7s. I actually like them more than the Avid Juicy hydraulics on the other two bikes we have.
