Your call, naturally. But you did come here asking for advice.
But bear in mind what you can achieve with only 2 FD, and 3 makes it exponentially easier to play ATAT Skittles. AT 2 FD, you have a 1 in 9 chance of getting four pips. With 3, that skyrockets from 11% to about 70%. And we just saw what you can do with that. The game is pretty balanced for the most part; even one extra Force dice makes a massive difference.
Just be aware that allowing easy access to Force dice will seriously impact the way your game plays.
