Replying to Too sketchy??

I ski a pair of  rossi ghettos, and love em. But i'm scarred of hitting rails because of their weak edges and i don't have the money right now to throw and get a new pair of sticks if i tear an edge out.

Just bought a pretty beat up pair of addict pros off gear trade for 30 beans to work on rails and what not.  I plan on using a pair of old demo bindings i have:/  .... and was planning on mounting them my self ( i have never mounted bindings before).  Paying $50 to mount $30 skis and garbage demo bindings is kinda backwards.

my question. Is this a recipe for death? I will not be  hucking clifs/60 footers with these. Anyone have experience or tips with home mounting. thanks
