1) The AI may have some difficulty with mounts that have downsides. They will always use the last mount in the list.

2) Beware the overpowered Stock mounts.
I suggest, as a maximum, +50% damage/kt on your very largest mount.

3) In carrier battles mod, I have the weapons range from around 2kt to 50kt, with only a +50% damage/kt modifier on the biggest ones. Accuracy bonuses range from +40% to -20%
As a result, the smallest mount is good against missiles and small fighters, while the middle mounts are good general purpose, and the largest couple mounts are required for damaging shielded ships (due to the higher damage per hit vs leaky shields and armor).
