We've got a set on our 2007 crv. There's a lot of posts out about them. Ours are at 30k and all is well. We use the car to commute over a 9000 foot pass a few times a week, so there's snow and ice. I have seen the cs-4s recently at pepboys for a reasonable price. I'd use either one, and I'm assuming the cs4's are as quiet and basically the same performance as the mastercrafts.
