I recently bought the RRS Versa 24L, BH1, and L bracket for my 5D3. I shoot the 70-200f4 with no issues on stability. If you are prone to adding a teleconverter, I would recommend a lens collar and plate. That will keep things balanced better.
It is really pretty light for packing, the Carbon Fiber doesn't get cold like aluminum, and it is a good investment. If you are planning to step up, you may want to grab a bigger step. Otherwise, you will eventually feel the need to upgrade again, and it will cost you even more, as you have already gone 'part' of the way.
Like they say, "Pay me now, or pay me later."
Good luck, happy hunting.
