Sure man! Good advice. I have bunch of low level ships which could be leveled up to 15 as F.S. You're right let's keep it close to the minimum. If you don't mind putting other ship types as FS (say SS, CA, BB etc) we'll have higher versatility, up to you though. It's just the F.S. won't be able to load a drum (nah... if that's another factor to be controlled)

The reason I'm more inclined on #21 is that we shall have a strong comparison on levels. The one we did for #37 is similar to the "minimum FS and greatly exceeded total" scenario, which will tell us the effects from total level. But the one we're doing now for #21 is to test the combined effects from the two, which will be more noticable when they both exist.
