I assume the benefit of cables are they won't bend or break if you forget about them being down and go in reverse?
Here's some useful information.... sorry for the length of it!
With the Slidekicks, the tip pressure is about half of the traditional coil spring style (which helps relieve the tendency for trailer and shop floor scratches). The wear-tips are made of zinc-coated hardened bolt-stock stainless steel, harder than the spring steel traditional scratchers are made of.
Slidekicks work to create an ice spray in a slightly different way than the traditional design; The body of each Slidekicks has much more inertial mass than the single wire arm, therefore it is less reactive(slower in the spring-action dept.) to the passing terrain, therefore it causes the wear-tip to strike the frozen surface, which in turn performs like an axe to "chip" the ice and create spray.
When the rear skid is airborne, the Slidekicks stick straight-out to the side and down at a 45 degree angle away from the track..this is their natural position. It is the drag of the tips against the passing terrain that pull and twist the Slidekicks into their running position. The Slidekicks are always trying to get back to this natural repose every time they leave the surface, so basically you get two spring actions performing one chipping function. This combines to produce a heavy ice-particle spray every time the tip strikes the frozen surface, not just a consistent small spray.
What we found during testing:
* The Slidekicks obviously didn't break when we backed-up.
* They were impervious to side-slide breakage.
* They never hung on the track like the traditional design had a tendency to do.
* We kept the Slidekicks down in every snow type because there was no need to hook them up on the rails anymore, ..also wear was a now non-factor because they have replaceable tips and therefore no unneccessary worry that you're wearing out a $60 pair of scratchers.
* Ice-spray performance was more than adequate on medium to hard snow, good on can't-stomp-your-heel-into-it-snow and not adequate on glare ice(frozen, glassy surface).
* The "chipping" action of the Slidekicks is made clearly evident by a close comparison of the marks left from use on the bottom of the wear surfaces of both designs. The surface of the traditional ice scratcher design wear point is smooth and shiny, this clearly indicates a "rubbing" action. The surface of the wear points on the Slidekicks, however, are knicked and scarred like they've been banged against rocks. This wear pattern clearly indicates the more effective "chipping" action described herein.
So basically, Slidekicks work as designed.
The m**** of this story, PUT THE SLIDEKICKS ON AND FORGET ABOUT 'EM!
