Hi Abhay, as discussed in length on email I assure you that you will not be disappointed with your hunt with Sentinel. I think its a good idea to ask folks on this site as you have about Sentinel or any other outfit and to get that reassurance that you are making the right decision.
You will have a good hunt , you will be staying in very good accommodations / camps for both Buffalo and plains game . Your PH Richard is very experienced and will take great care to get you the animals that you are wanting to hunt. I honestly can't say more than what I have already .
If you are having second thoughts and can't make the dates or do this hunt then please advise accordingly , If you have sent a deposit and all is booked and set then great you will have a great time .
As explained before I am not available to do this hunt in the time frame that you are wanting to hunt , PH Richard Brebner knows that property very well and the owners the Bristows are great hosts and they take special pride in providing great safaris.
If I did not think that was the case I would not book hunts with them for myself and I would not be recommending them , but I do and you will be in great hands OK.
Best regards
Wayne
