Replying to To remount or not?

Last year I blew out the heel piece on my Bentchetlers. It ripped right out and when I took them to REI to see what they had to say about it they told me the core is shot and its too much of a liability to remount because it'll just rip out again. My problem is i love these skis, and i really want to ride them again this year but also don't know if its worth the risk of ripping them out again in possibly a worse spot and end up hurting myself. Should I move back and remount? or accept the fact that they are old beat up skis and build a chair?
