I use a nice combination of these skins for my game and I thought I might post my combination here for users!
Britain: 57th Regiment of Foot (Over 33rd)
France: Dutch Grenadiers (Over Old Guard)
Russia: Bulgarski Chetnici (Over Preobrazhensky)
Prussia: Continental Line Infantry (Over Landwher)
Now to get the unit's seperate names to appear in game because you cannot use each individual skins troops.txt file I edited the troops.txt file myself and replace for example 33rd_Regiment_of_Foot and typed in 57th_Regiment_of_Foot writing exactly as is named in the skins troops.txt
Great skins for a great combination Raddeo!
