Roman Legion composition?

[Lanceari]

...It has been repeatedly pointed to you now that people are criticizing your over use of Pedites Extraordinarii and Triarii, not the use of local skirmishers. Triarii were the oldest (or wealthiest) of heavy infantry, only to be used if needed. Pedites Extraordinarii made up even a smaller proportion of the army, and certainly were not line infantry either.

In my very first post I stated:

Most of the time I keep a large contingent of local inexpensive troops... since I can replace casualties locally. However, I tend to have more than the historical share of triariis...

I use quinqux like formations when I deploy my units, except that I use my Triariis to back up both my Roman Legionaries and my non-Roman units. That is the main reason I end up having so many triariis. Again, in my fist post I said:

I use triariis as a second (or third) line for... my legionaries and my locally raised units.

From the very start I pointed out I was using more than the historical share of trariis. And, I pointed out the reason for it. You all want to share your thoughts on my choice. Thank you.

As far as pedites... Pedites make the tinniest fraction of my total army (less than 1% of all my units in the campaign map). However, I concentrate them all on the one stack I use for assaulting cities w/ stone walls.

In my first post I explained I use different stacks for different terrains (Woods, Open Country, Cities with Stone Walls, Cities W/out Stone Walls). Do you use the same unit composition to fight in each different type of terrain?
