Well, in my version of the Brets, here are the following tweaks I'd recommend:
Leader - drop to 70gc (NO reason it's as high as 80.)
Errant - may take comb, strength, & speed (and special)
Squire - may take comb at & SPEED (instead of strength)
Squire only skill:
Knight errantry - the squire may choose to become a knight errant. He gains the skill "Knightly Virtue" and access to the Bret Special skills. As a knight, he must immediately switch his equipment over to the Knight equipment, forsaking all missile weapons.
If I were to completely redo the warband, I'd replace the lady's blessing with lucky charms, make squires a henchmen group instead of a hero group, and make the special skills more practical (shield bash, bulging muscles), but eh, that's only the ranting of crazed nerdboy.
