It was something on the DIS list about new EU/HSE regs IIRC - basically, the cylinders are going to be heavier, therefore loosing the buoyancy properties that made them popular as stages.
So yeah, you can still get Luxfer cylinders, but there won't be any point, they'll be no different to steels. In fact, you might well be better off with a lightweight steel.
There's even been talk of importing US Alu cylinders... |
