Replying to Rossignol axial 2 or rossignol fks

ok so ive been looking for bindings to put on my on3p filthy riches and im stuck between the rossi fks/look pivots (same binding) rossignol axial2 or the look px 12, btw are those two the same binding also. ive been reading on how the pivoting bindings prevent acl tears but they also break really easily and there alot more expensive. ive only been skiing for a year but can backflip are acl tears for more advanced skiers or is everyone vulnerable to them? im 5"9 175 so im a bit bigger and i ski with my marker squire dins at 8 and i rarely eject when i fall. any opinions would be nice also other binding suggestions would be nice to
