I am going with a historical type Fleet for the Indian Ocean Jonas.
100 gun ship, Admiral as Flag, based in Capetown, a 74, Commodore based in Calcutta. Three Frigates to patrol the Ocean, and a Sloop to do all the donkey work. Up against them I will have two 40 gun French Frigates, a 38 and a 34 plus two Sloops. That was the French Indian Ocean force which gave the RN and the HEIC a hard time of it. I will balance up the odds as I play each scenario out. As I don't actually count points in my games, it won't matter what I decide to do. it will not effect any of your chaps results.
Free kriegsspeil covers most of the problems which have been voiced here so far.
As long as you all enjoy the game it is all that matters. Don't straight jacket yourselves with too many rules or you will not get a good game out of it.
Rob.
