Philip, you will love Masailand, that was my first hunt in Africa. Around Mto-Wa-Mbu and surrounds. Classic safari country. Oddly enough buffalo are not always a sure thing in that area but I did manage one there, though it was many years ago now, 1985. Also took good examples of Grants, Thompsons, impala, hog, zebra and white bearded gnu. We drove from Arusha to the hunting area and it was long and painful but no expensive charter. Hope you can make that happen.
