Thoughts on Morale?

Hey all!

I am playing a game of 10mm Napoleonics using my house rules, Brigades and Bearskins!

I am still making changes as I go (for example, I am changing the charge mechanic, and changing how officers move a bit) but one thing that I think needs work is the MORALE.

At the end of each round, brigades that are in combat must take morale tests to see if they are starting to waver.  They roll on 1d6.

Right now, British units that are unharmed and otherwise neutral pass on a 2+.  French troops and Brunswickers pass on a 3+.  This counts for ALL troops; infantry, cavalry, etc.

There ARE modifiers... elites get a +1 on their role, troops in column get a +1... units that have taken damage get a minus, up to a max of -4.

So, right now I am wondering if my basic morale stats are good!

What do folks think?  What should the morale of British cavalries be?  What about Frenchies? 

ANY advice or suggestions are welcome!
