Late in the game when you have 30 or more family members "sharp/charismatic/vigorous" will not matter that much. I try to accept FM on their name ( if I have a dozen or so Cornelius Scipio and Fabius Maximus I drop him, and age preferably between 16 and 25). Its 158 in my currunt Roman campaign, and my previous year consul was in Iberia. In that same year an Aediu full stalk marched from Avaricum, and as I had only one full legion in Italia they captured Mediolanum. In that same year I had 3 Consuls. Two where in Iberia and had quite a lot of influence, and the third one!. Well its seemed to time that the Ai senate responded to the Gallic invasion my electing a new consul in Italia, Gnaeus Aurelius Cotta. He was elected to all previous magistrate posts, had never been at the wars, was sharp, uncharismatic and dull, with only a few influence. But for capturing Mediolanum, defeating the gauls and sacking Avaricum he got a Triumph. Thats why I like EB, it was an amazing event. But as said above late in the game magistrate post will be awarded to a lot of you FM, patience is the key.

Cheers.
