I started using Westco with my R1100R back around 2000 (+ or - a few years). I have been using them ever since. I have to say a couple of been better than others which adds credit to what DR is saying. I have thought about going to the PC680 as I keep hearing about them from a variety of forums. Be interesting which you pick.
