Regarding ship specs.
If two ships use identical saucer size (or command boom) weapons, impulse and warp systems have them use the same numbers.
It really frosts me that most of the TMP fleets use the same weapons, warp engines and impulse and rarely do they have the same BASIC stats. I get that some ships have more or less weapons or are specialized but BASIC stuff should remain identical. FASA Trek contradicted itself repeatedly in this area. The Chandley is depicted in FASA Trek illustrations with TMP warp engines has the same weapons as a TMP Enterprise Class (Connie refit) but the stats reflect a TOS Enterprise warp engines...
Fleetdock13 had it right. The models used in SFB OP look like the ship designers used the same measuring stick for ship components. Ideally this should also translate into identical stats for standard power, weapons, etc.
FASA tried this with their TMP era Trek games but didn't really hone the idea until they published Battletech. In Battletech, mechs with specific engines, weapons and armor can be comparably spec'd to other mechs. Eventually players get to the point where at a glance they already know that a 25 ton mech is probably not going to hold its own by itself against a 75 ton mech for instance.
Just some thoughts.
