Replying to Line reactor binding

KNOW WHAT YOU ARE TALKING ABOUT BEFORE ANSWERING

ok soo I tore my acl last year and now im worried about skiing and tearing it again. I wont go into details but it was a very slow backward twisting fall. This binding says it will release on backward twisting falls, but will it release on slow backard falls and also will it pre release when i dont want it to. Also I know that the first edition was terrible quality and they say this one is better so if anyone has any info at all that would be great. Also if anyone knows someone who really knows there knees and bindings that i could get incontact with that would be great. thanks
