50 would or more would be great...stuff like something the size of a python, but with a bit less cargo area, a Better FSD and another hardpoint
50 or so would only be great for me if they chose to include ships that fill empty niches, not just extra ships in niches that already have plenty of choices. So Imperial eagles, viper and cobra mark IVs may be great ships, but they hardly break new ground. There is no better explorer above the Asp until you get to the Anaconda.
