As the thread title says, I want to understand the differences between the two. Both SEEM to offer better thrust and improved top speed, but I can't work out which gives better top speed overall ... and why! The parameters don't seem clear (not to me anyway!) in the description as to EXACTLY what effect they have! Which is better for Exploration, and which for combat? The engineer 'blurb' suggests BOTH are good for exploration, but then there's other comments and parameters that vary that I can't quite get my head around as to exactly what effect they have. Anyone care to spell it out in plain english? Please?
