Modifying Pikemen to Use Pikes Only?

[Machiavelli]

Note - there are "pike fix" mods that remove the sword, forcing the pikemen to use pikes all the time. However, these arguably make the pikemen too strong.

After considerable struggle with the pikemen of M2TW switching to swords when they least need them, I've come to the conclusion that my campaign game isn't worth the trouble of keeping vanilla pikes.

Granted, the Citadel FAQ says they're "arguably too strong" but I could care less.

So my question is this: What file do I need to modify to alter medieval 2 pikemen, and what variables should I change so that pikemen use pikes at all times? I'd like to remove their secondary weapon entirely.
