I can't comment on any of the lenses as I don't own them (other than I would love to own them). I have been to the Serengeti twice, originating from USA.
I would strongly advise you to check with your tour operator and airlines regarding size/weight restrictions. Also, there are many differences in tours, so some make longer lenses absolutely necessary.
In any event, you don't want make all these changes only to find out that the gear needs to stay at home.
As an example, when I checked in to KLM Dutch at DFW Airport, my camera bag was over weight (max as I recall was 12 KG). I stuffed the heavy lenses in my safari vest. Then when we left Arusha for the Serengeti, we took a puddle jumper for 1:45 min. They were very strict on weight requirements (bags however went behind seats). You also have to check, as some connecting flights have small overhead compartments. All of these details are critical when you are taking large heavy gear.
Hope you have a great trip, keep us posted.
Good luck with the lenses
