Poll: Ship design strategy

[Suicide Junkie]

There are a number of basic ship design strategies; some of these can only be done effectively with a quasi-newtonian propulsion mod.

Nimble & frail: Ships are faster than anything else around, and lack any shields or armor. Theory: You can't lose if the enemy can't hit you.

SwarmShips: Twice the ships, half the size. Weak offense/defense due to size, but tens to hundreds of ships at a time. Theory: Rapid building, safety in numbers, finer control over fleet composition.

MuscleShips: All weapons, with token defenses, and moderate speed. Theory: You can't lose if the enemy is already dead.

FortressShips: All systems organized for defense. Heavy shields/armor, lots of protection against specialty weapons. Moderate speed, few weapons. Theory: If they can't hurt you, you can't lose.

I am deeply devoted to the FortressShip. I've designed and built $100,000 DNs with that goal in mind.
My dad goes for the nimble & frail. Zero KT of defense, but 13+ movement ships that rarely get hit.

Which do you fall under? Or do you have your own style?
