I'm sorry, what? I thought you could only get metallic hydrogen with gas-giant core pressures and temperatures. Metallic hydrogen is theoretically meta-stable. We'll find out soon if that's true, as a research group claimed a few months back the successfully made metallic hydrogen. Last I checked there was plenty of speculation on what properties MSMH might have, but basically every paper ended with 'but we have no idea how to make it or even it it's actually possible'.

Well, this thing still sounds good, though.
Liquid/Gas/Plasma core NTR, along with antimatter drives will probably exist as black box engines in Project Prosperous, so I am looking forward to this.

This thing isn't even blackbox, we can for the most part model it quite accurately.

Honestly, the biggest advantage I see for metallic hydrogen is we no longer have to choose between exhaust velocity and propellant density. By storing hydrogen as a solid we can have the tank density of mercury (well okay it might not be *that* dense, it's still made of hydrogen) while still enjoying the exhaust velocity of hydrogen!
F-H chemical rockets might get a lot more interesting too...
