hi,
if you are able to follow the sun around, meaning it is always backlighting your angles then all you need are silks to control the amount of fill in front. depending in what part of the world you are shooting in, the sun may stay low in the horizon (unlike here in the philippines where at this time of the year it goes directly overhead at 90degrees) in which case you stage the widest shots earliest in the morning or latest in the afternoon and shooting the tighter shots midday where the height of the sun may not be so noticeable.
