First 80 psi then 100 psi and then 150 psi then what?

Fizzy bottles were not designed for anything other than to contain fizzy drinks. Are we to type test every fizzy drink bottle on the shelves of Tescos? Their manufacturing properties will differ as will their burst pressure. Their burst pressure will vary with temperature (hot air from that little car tyre compressor), how do you monitor fatigue? If you crease the plastic by accident as a vented bottle is rather weak, should it be rejected? There are just too many variables with fizzy bottles for me to feel confortable using them at pressures above 50 psi.

Keep the fizzy bottles to the RRC bots, there are other more suitable alternatives for the bigger boys wanting higher pressure.
