I was just about to say the same!
Being a South African and hunting every year its basically second nature shooting off of sticks.
It would be wise to ask the PH what sticks he plans on using as there are many different types.
And OP is correct in asking what to feel as there is a HUGE difference in how they all feel. This is due to the relationship between where the sticks are in connection to the shooter. Even the "rest" for the rifle. Some like trigger stick feels awkward because the handle is below the "rest". Some like the vangaurd tripod feels bulky and you dont know where to place your support hand. All this is obviously subjective, but can put a "new to stick" shooter off. So try as many as possible and see what feels the best. For 150yards and closer then a tripod of some sort will be perfect. If 200+yards is on the table then a quad stick will be more stable ,but also takes longer to set up and unless you are well trained with them ,they will be somewhat thumbly and awkward to get onto quickly.
ALL OF THIS IS RELEVANT! BUT ALSO NOT! At the end of the day if you practice a bit and dont OVERTHINK it you will be fine.
For example here is a pair i made last week for my upcoming hunt end of April. As mentioned i am from Africa and have shot off of many sticks, so i decided to combine everything i like into 1 shooting stick. I dont like the handle of the trigger stick, i dont like the standard 'V' or ' U' nodge rest for the rifle and i dont like that quad sticks cant stand alone. WHAT i do like is having a flat base such as a sand bag or when shooting off of my pack. I like that a tripod can stand alone without my support. I like that i can QUICKLY deploy the tripod and get on it and comfortable. And lastly i like the "traditional " wooden look, so hence i made a wooden tripod with a flat base with a sponge covered in artificial leather. With a parracord handle to prevent rattle noise(and you never know when a bit of rope can come in handy) and rubber feet for non slip regardless of terain.
