We are certainly not high performance skiers in my family, but weekend duffers who go out for a couple of sessions on a weekend. I'd like to get a new handle and line and am trying to figure how this can make a difference and wear out as fast as I see some claim. Does the line stretch in a way that makes one perform better than another? Is there one style of handle that is preferable for slalom skiing? We aren't going through a course, just trying to make a nice turn linked to the next one.
