Paul keep it simple - your PH will advise you best - don't be afraid to ask him - you are paying for it besides your good preparation will serve both parties well once the hunt is on its way - at all my crossings the water was max. bit over knee deep - my next time in the area will probably be in a late/very late season so even mornings will be warm and I will be wearing my Teva rafters.

P.S. John when I shot the bushbuck and went to the spot where it was standing - your signature came to my mind - smell of the cordite hangng in a still air of a moisty warm morning...eish - unforgetable
