It certainly sounds like you have the symptoms of high pressure.
I would do whatever it takes to use the braided supply. They are bullet proof.
I have seen more leaking plastic lines than I care to imagine. Copper also has a tendency to get kinked when you move the fridge in and out to clean the coils. (some people actually do that it makes them last a long time) Once kinked the leak is following soon if not immediately. Usually it is just a matter of drilling a hole down through the floor.
