I agree that there is a certain formula that Gene Rodenberry used which held true for the most part. I am all for more ships added to STO, but I would strongly suggest that the graphics artists stick to the traditional layout of a Saucer, two (or four nacelles), and an engineering hull. The Long Range Science Vessle is ok, but really should have had a clearly defined Saucer. The Star Cruiser was much more in line with the tradtional designs, but it could have a more rounded saucer. It was a good start and I encourage the design teams to contiune to bring us more ships.
