Replying to Guardian 2016`s

Hello
anyone think that the Salomon guardian 16 15/16 model have any of those early troubles with breaking the metal guiderails?

mostly going to be used as a lift up ski down in pow, but need to have the opportunity to skin up if needed :) and i can get a decent price on guardian`s :)

going to be mounted on my salomon rocker2-108 190 since my STH2 16 is getting mounted onto my NFX lab 176`s :) the 190`s was alittle to burly in the tight forrests of Norway :D
