Nice hit with the new stats.
Some time ago i modded small (1 tube) and large (5 tube) Pilums to complement the medium one. It is not best in terms of balance with stock pilums, but with your stats even small launchers are fairly usable, without becoming overpowered.
If you want i can publish link to your mod with small and large launchers added.
BTW: I also had versions with different color markings housing shrapnel warhead, salvo of 3 emp bomblets or single swarmer SRM. Stopped updating them somewhere around 6.3, as various mods offered more interesting alternatives.
