Hi Bill,
Cluck here. I've played both. You saw my post on Muskets and Mohawks so should have a basic understanding of how it plays. It is really designed for small battles rather than skirmishes. The key difference between M&M and M&T is that M&M's 10-man units behave more like units in that all of the soldiers in the unit maintain a formation (even if it is "skirmish") and all perform the same action, whereas in M&T, though the units are similar in size (between 6 and 12 soldiers generally), the soldiers can perform different actions each turn. M&M shines with more units/figures than you are contemplating; M&T may give you a more engaging game experience.
If you like the THW mechanics, check out the man-to-man version for the F&IW, Long Rifle.
