Hi does anyone have any experience with taking mounted forces to tournaments, as I was hoping to get advice on how many dismounted infantry models I should take for the following list;

Erkenbrand (Horse)

Rohan Royal Guard x 4 (Throwing Spears, Horses)

Riders of Rohan x 4 (Throwing Spears)

Riders of Rohan x 6 (Bows)

Riders of Rohan x 5 (Hand Weapons)

The reason I ask is that I havent played the game many times and don't really have any idea how frequently riders are dismounted, so I dont know whether I need one infantry for each cavalry or whether I can get away with only a couple of infantry models.

2 of each should be enough.
