How to beat Crystallurgy with Organic?

[Jubala]

All good ideas, thanks guys. There's only one little problem. My enemy uses a mixed fleet with one type of ship armed with PPB's and another type armed with Shard Cannons. I can design a counter for each of those designs that whip them good, but then that design is a complete sitting duck for the other enemy design. If I try to design a ship that can stand up to both of them it gets clobbered by both of them. And since there is no way to control which ships engage which enemy ships in strategic combat (pbem game) building two designs that can beat one of his but is mauled by the other doesn't seem very appealing.
