I am currently tweaking with a small reconnaissance frigate, and I'm still not able to decide whether I should opt for engines which allow it to do an high speed dash or a steady cruise at faster speeds. So I'd like to take advice, what would you do for a ship whose duty is mostly reconnaissance, go for a better rounded speeds which allow the ship to go faster for a good amount of time, or the engines which are a tad slower, but that will permit very high speeds for shorter durations
For a recon ship, I would give it the engines that can give it a short burst of speed. My reasoning is that reconaissance wouldn't often need speed, except to get away from pursuers. Better be able to outrun anything you can't outgun, and that's likely just about everything for a little recon craft.
